Consider these ratio scores from an experiment: Condition 1 Condition 2 Condition 3 18 8 3 13 11 9 9 6 5 (a) What should you do to summarize the experiment? Comparing the results in questions 19 and 22 buy cipro 250mg otc, which experiment produced the stronger relationship? What are the three major pieces of information we need in order to summarize the scores in any data? What is the difference between what a measure of central tendency tells us and what a measure of variability tells us? For each of the following best cipro 250 mg, identify the conditions of the independent variable buy cipro 250 mg otc, the dependent variable discount 750 mg cipro otc, their scales of measurement, which measure of central tendency and variability to compute and which scores you would use in the com- putations.

The computational formula for estimating the population variance is Range highest score lowest score 1©X22 ©X2 2 2. The computational formula for the sample N s2 5 variance is X N 2 1 1©X22 ©X2 2 5. Your goals in this chapter are to learn ■ What a z-score is and what it tells you about a raw score’s relative standing. The techniques discussed in the preceding chapters for graphing, measuring central tendency, and measuring variability comprise the descriptive procedures used in most behavioral research. In this chapter, we’ll combine these procedures to answer another question about data: How does any one particular score compare to the other scores in a sample or population? In the following sections, we discuss (1) the logic of z-scores and their simple com- putation, (2) how z-scores are used to describe individual scores, and (3) how z-scores are used to describe sample means. The size of a number, regardless of its sign, is the absolute value of the number. When we do not ignore the sign, you’ll encounter the symbol ;, which means “plus or minus. Saying “the scores between ;1,” means all possible scores from 21, through 0, up to and including 11. Recall that we transform raw scores to make different variables comparable and to make scores within the same distribution easier to interpret. The “z-transformation” is the Rolls-Royce of transformations because with it we can compare and interpret scores from virtually any normal distribution of interval or ratio scores. Because researchers usually don’t know how to inter- pret someone’s raw score: Usually, we won’t know whether, in nature, a score should be considered high or low, good, bad, or what. Instead, the best we can do is compare a score to the other scores in the distribution, describing the score’s relative standing. Relative standing reflects the systematic evaluation of a score relative to the sample or population in which the score occurs. The way to calculate the relative standing of a score is to transform it into a z-score. As you’ll see, with z-scores we can easily deter- mine the underlying raw score’s location in a distribution, its relative and simple frequency, and its percentile. All of this helps us to know whether the individual’s raw score was relatively good, bad, or in-between. Of these scores, we espe- cially want to interpret those of three men: Slug, who scored 35; Binky, who scored 65; and Biff, who scored 90. What’s worse, down in the tail, the height of the curve above your score indicates a low frequency, so not many men received this low score. Also, the pro- portion of the area under the curve at your score is small, so the relative frequency— the proportion of all men receiving your score—is low. Finally, Slug, your percentile is low, so a small percentage scored below you while a large percentage scored above you. So Slug, scores such as yours are relatively infrequent, and few scores are lower than yours. Also, the area under the curve at your score is relatively large, and thus the relative fre- quency of equally attractive men is large. In fact, as you have repeatedly told everyone, you are one of the most attractive men around. Also, the area under the curve at your score is quite small, so only a small proportion of men are equally attractive. Finally, the area under the curve to the left of your score is relatively large, so if we cared to figure it out, we’d find that you are at a very high percentile, with only a small percentage above you.

Both mitosis and meiosis cheap cipro 250 mg visa, designated as M buy cipro 250 mg on line, consist of four phases: prophase safe cipro 1000 mg, metaphase order cipro 250mg with amex, anaphase 1000 mg cipro free shipping, and telophase. Each of these phases involves the rearrangement of the number of chromosomes and represents the pro- gression of cell division (Fig. In prophase, the chromosome thickens in the shape of dumbbell with a constriction at the center, called centromere. The nuclear membrane breaks open, leading to the mixture of cytoplasm and nuclear material, and spin- dles made of fibers are formed extending from one end (pole) of the cell to the other. Next in the metaphase, the chromosomes move to and line up at the central (or equatorial) plane of the cell, and the centromeres divide into two, each attaching to the spindle. The last step of cell division involves the deconvolution of the chromosomes leading to the regenera- tion of the nuclear membrane and nucleoli around both poles. Division of cytoplasm (cytokinesis) sets in, and ultimately two daughter cells are formed. The period between the telophase and the S phase is termed G1, and the period between the S phase and the prophase is termed G2 (Fig. During the G1 and G2 periods, no functional activity related to cell division occurs. The period of the entire cell cycle including the M and S phases varies with the types of cells. The S phase normally is the longest and G1 is the most variable phase in the cell cycle. M is the period of mitosis during which the prophase, metaphase, anaphase, and telophase take place. G1 is the period between the telophase and S, and G2 is the period between S and the prophase. It has a double-helical structure consisting of two strands, which are like the two rails of a ladder (Fig. The two strands are connected to each other by rungs made of four bases: thymine (T), adenine (A), guanine (G), and cytosine (C) (Fig. The rungs of the ladderlike structure are formed by bases connected to each other by the hydrogen band (dashed line) and to the sugar molecule on the strands on both sides. Effects of Radiation 231 cule on the strands on both sides, and are paired to each other by hydro- gen bonds. These four bases are arranged in a very specific manner to form a specific gene in every living species and provide the unique characteris- tics to these species. These changes result in so-called mutations, which have adverse effects on the genetic codes. At low-dose exposures, the breaks are single stranded and can be repaired by joining the broken components in the original order. At higher exposures, however, double strand breaks occur and the odds for repair decrease. If the cell is not repaired, it may suffer a minor functional impairment or a major consequence (cell death). However, chromosomes themselves can be cleaved by radiation producing single or double breaks in the arms. These aberrations are categorized as chromatid aberrations and chromosome aberrations. Whether chromosome aberrations are induced by single-strand breaks or double-strand breaks in the structure determines the fate of the cell. In single-strand breaks, the chromosome tends to repair by joining the two fragments in a process called restitution, provided sufficient time is allowed. Random combination of these fragments will then produce acentric and dicentric chromatids as illustrated in Figure 15. Such chromosomes suffer severe consequences due to the mismatch of genetic information.

However, these cells suffer severe consequences because of the mismatch of genetic information from two separate damaged chromosomes. The translocation is a process in which two fragments—one with a centromere from one chromosome and one without a centromere from another chromosome—combine to form a new chromosome (Fig. In another scenario, radiation can cause two breaks in one arm of a chromosome, resulting in three fragments, only two of which combine with the loss of the third.

However cipro 250 mg sale, this should not be at the expense of excessive delay in referring those patients with more severe malocclusions who may gain some benefit from simple interceptive measures purchase cipro 500 mg on-line. Prognosis of teeth The family dentist is in a much better position than the orthodontist to estimate the prognosis of restored or traumatized teeth generic 750mg cipro overnight delivery. Radiographs Any relevant radiographs should be forwarded with the referral to avoid unnecessary repetition cheap cipro 250mg online. Key Points Screening • All children should be screened for malocclusion from 8 years of age order cipro 1000 mg. The extraction of teeth in the mixed dentition for purely orthodontic reasons, usually crowding, can sometimes be helpful, but managing the enforced extraction of carious or poor quality teeth is a matter of trying to minimize disruption of the developing dentition. Usually, it is the teeth distal to the extraction that migrate forwards as a result of mesial drift. This drifting is generally unhelpful where the extraction is enforced, but in some situations it can be harnessed to help with the management of dental crowding. As there is a significant increase in the size of the arches during the mixed dentition stage, decisions about the treatment of crowding should be deferred until the permanent incisors have erupted for at least a year, usually at about 8 1/2 - 9 years of age. Where there is severe crowding, the extraction of primary teeth may be considered at this point as part of a programme of serial extractions, but where the crowding is mild the decision should be delayed until the permanent canines and premolars are erupting. Primary canines⎯extracted as the permanent lateral incisors erupt to allow them space to align. First primary molars⎯about 1 year later, or when the roots of the first primary molars are half resorbed or more, to encourage eruption of the first premolars. First premolars⎯on eruption to make space for the eruption of the permanent canines into alignment. In effect, the extraction of primary canines transfers the crowding from the incisors to the canine regions where it is more easily treated by extracting the first premolars (Fig. It is essential to carry out a full orthodontic assessment before embarking on a course of serial extractions. The indications for serial extraction are: (1) significant incisor crowding; (2) patient aged about 9 years; (3) class I occlusion without a deep overbite; (4) all permanent teeth present; (5) first permanent molars in good condition. The intended advantage of serial extraction is to minimize or eliminate the need for appliances to align the arches after the permanent teeth have erupted. Where crowding is severe it may be necessary to fit a space maintainer following extraction of the first premolars, to ensure that mesial drift of posterior teeth does not leave the canines short of space (see Section 14. The great disadvantage of serial extraction is the multiple episodes of extractions, starting when the child is quite young. The likely benefit of the extractions must be considered very carefully, and in only a small minority of cases would general anaesthesia be justified for this purpose. In practice, the extraction of the first primary molars is usually omitted, and the decision thus becomes whether the primary canines should be extracted. Extraction of these teeth might be indicated where it is clear that orthodontic appliances should be minimized or avoided for some reason, or where the crowding is obviously severe and is causing gross incisor displacement or cross-bite. It is also sometimes indicated to encourage the eruption of an ectopic permanent tooth (see Section 14. However, it must always be borne in mind that the extractions will allow some mesial migration of the buccal segments, so increasing the crowding. The extractions should always be balanced by removing the contralateral canine to prevent a centreline shift, but it is not necessary to compensate by extracting the canines in the opposite arch. The primary first molars are extracted to encourage eruption of the first premolars. Mesial drift is greatest where there is a tendency to crowding, and it also becomes greater the more distal the tooth to be extracted is. It is greater in the upper arch than in the lower, as the upper permanent molars are distally inclined on eruption and readily move mesially by uprighting, whereas the lower permanent molars are mesially inclined on eruption and move forward less readily, but tilt mesially as they do so. Extraction of primary incisors usually causes virtually no drifting of other teeth, but if done very early may delay the eruption of the permanent incisors. There is also drift of the incisors into the space, which causes a centreline shift towards the extraction site. This should be prevented by balancing the extraction with loss of the contralateral canine. In the same way the extraction of a primary first molar allows mesial drift of the teeth distal to it, more than with the loss of a canine, and there may also be some effect on the centreline.
