To calculate the percentile rank, divide this number of countries by the total number of cases and multiply by 100: Pr ⫽ B 12 ⫻ 100 ⫽ ⫻ 100 ⫽ .67 ⫻ 100 ⫽ 67 N 18 Thus, Italy is in the 67th percentile rank, or the 67th percentile in this example is 5.72/1000 or 5.72 deaths per 1000 live births. . For household incomes greater than $100,000, the government only reports incomes using class intervals of $50,000. Special thanks go to Danielle Zuest and Nancy E. Johnson. The frequency distribution displays scores on a variable or a measure to reflect how frequently each value was obtained. The Evolution of Intelligence and Standardized Achievement Tests The history and evolution of Binet’s intelligence test are instructive. When a scale has the property of equal intervals, the relationship between the measured units and some outcome can be described by a straight line or a linear equation in the form Y ⫽ a ⫹ bX. X is the mean; it is pronounced “X bar.” Σ is the summation sign. . . Their use proliferated widely. Further, because many psychologists associated tests with this secondary relationship, they rejected testing (Lewandowski & Saccuzzo, 1976). To find the proportion of the distribution between the mean of the distribution and a given Z score, you must locate the entry indicated by a specific Z score. . 88 90 32 CHAPTER 2 ■ Norms and Basic Statistics for Testing the center of the distribution, around 75 and 76.

Shortly after the United States became actively involved in World War I, the army requested the assistance of Robert Yerkes, who was then the president of the American Psychological Association (see Yerkes, 1921). . . Thus, for a negative Z score, we can obtain the proportion of cases falling below the score by subtracting .2734, the tabled value listed in the appendix, from .5. From the roots of psychology to the present, psychological tests have remained among the most important instruments of the psychologist in general and of those who apply psychology in particular. Few students who want to go to a 4-year college can avoid taking a college entrance test. Optimistic people tend to remain so regardless of whether or not things are going well.

Not only has the interview traditionally served as a major technique of gathering psychological information in general, but also data from interviews provide an important complement to test results. In Chapter 11, we cover testing in education with an emphasis on special education. . In school settings, standardized achievement tests allowed one to maintain identical testing conditions and scoring standards for a large number of children. . CHAPTER 1 ■ Introduction 23 Modern history shows that psychological tests have evolved in a complicated environment in which hostile and friendly forces have produced a balance characterized by innovation and a continuous quest for better methods. The meaning of the scores can change dramatically, depending on how a well-defined sample of individuals scores on a test. And, of course, when we get into college we face still more tests. After the British endorsement of a civil service testing system, the French and German governments followed suit. If you are using the table correctly, you should obtain 86.43. It is interesting, as we shall discuss later in the book, that teachers of today appear to have come full circle. Statistical methods serve two important purposes in the quest for scientific understanding. There were far fewer applications of psychological testing than there are today.

If you are in the top 15% of the class, you will get an A (85th percentile or above); between the 60th and the 84th percentiles, a B; between the 20th and the 59th percentiles, a C; between the 6th and the 19th percentiles, a D; and in the 5th percentile or below, an F. Using Appendix 1, you should be able to find the Z scores associated with each of these cutoff points for normal distributions of scores. Tests are presently in use in developed countries throughout the world (Marsh, Hau, Artelt, Baumet, & Peschar, 2006; Black & William, 2007). Kaplan currently serves on the National Advisory Committee for the Decade of Behavior. Because some households have extremely high incomes, you can imagine that the tail of this distribution would go very far to the right.

Inferential statistics are methods used to make inferences from observations of a small group of people known as a sample to a larger group of individuals known as a population. CHAPTER 1 ■ Introduction 21 For better or worse, depending on one’s perspective, the government’s efforts to stimulate the development of applied aspects of psychology, especially clinical psychology, were extremely successful. . The three distributions of scores appear quite different but have the same mean, so it is important to consider other characteristics of the distribution of scores besides the mean. Nominal scales are used when the information is qualitative rather than quantitative.

If you have had a course in psychological statistics, then this chapter will reinforce the basic concepts you have already learned. What does it mean when someone gets 75 items correct on a 100-item test? To get rid of the decimal points, you multiply by 100. Indeed, several new and exciting developments in data analysis allow extensive and detailed use of nominal data (Chen, 2002; Miller, Scurfield, Drga, Galvin, & Whitmore, 2002; Stout, 2002). . For example, the Z score −1.6 is associated with the percentile rank of 5.48. He is a past chair of the Behavioral Science Council of the American Thoracic Society. to 220 C.E.

For example, we see that 34.13% or .3413 of the cases fall between the mean and one standard deviation above the mean. Binet’s standardization sample consisted of 50 children who had been given the test under standard conditions—that is, with precisely the same instructions and format. . The main use of these tests, though, is to evaluate individual differences or variations among individuals. Instead of using Z scores to find the percentile ranks, you can use the percentile ranks to find the corresponding Z scores. To make this into a percentile (as shown in Part I of the appendix), multiply by 100 to get 84.13. In the section on the normal distribution, we explain this concept in greater detail. . . . 36 CHAPTER 2 ■ Norms and Basic Statistics for Testing PSYCHOLOGICAL TESTING IN E V ERYDAY LIFE 2.1 Infant Mortality in Selected Countries, 2007 Infant Mortality per 1000 Live Births Country Afghanistan Australia 157.0 4.6 Bolivia 45.6 China 23.0 Colombia 19.1 Ethiopia 86.9 France 3.4 Israel 6.8 Italy 5.7 Japan 2.8 Laos 51.4 Morocco 30.6 Mozambique 95.9 Saudi Arabia 18.8 Singapore 2.3 Spain 4.3 Turkey 27.5 United States 6.4 Mean 32.9 SD 41.9 To calculate the percentile rank of infant mortality in the United States in comparison to that in selected countries, use the following formula: Pr ⫽ where B ⫻100 N Pr ⫽ the percentile rank B ⫽ the number of cases with worse rates than the case of interest N ⫽ the total number of cases CHAPTER 2 Country ■ Norms and Basic Statistics for Testing Infant Mortality per 1000 Live Births Singapore 2.3 Japan 2.8 France 3.4 Spain 4.3 Australia 4.6 Italy 5.7 United States 6.4 Israel 6.8 Saudi Arabia 18.8 Colombia 19.1 China 23.0 Turkey 27.5 Morocco 30.6 Bolivia 45.6 Laos 51.4 Ethiopia 86.9 Mozambique 95.9 Afghanistan 157.0 STEPS 1. Koen.) The chronological age of the child may be 4 or 12, but in terms of test performance, the child functions at the same level as the average 8-year-old. . Traits are relatively enduring dispositions (tendencies to act, think, or feel in a certain manner in any given circumstance) that distinguish one individual from another. Part I of Appendix 1 is a simplified version of Part II, which you need for more advanced use of Z scores. Z Score One problem with means and standard deviations is that they do not convey enough information for us to make meaningful assessments or accurate interpretations of data. A score that is one standard deviation below the mean would be about the 16th percentile rank (50 − 34.13 = 15.87). Our partners will collect data and use cookies for ad personalization and measurement. Figure 2.7 shows the theoretical distribution of heads in an infinite number of fl ips of the coin. In contrast, we view psychological testing as an exciting field. Clear explanation, nice language, good illustrations, and graphics. Note: Citations are based on reference standards. .

When a scale has the properties of magnitude and equal intervals but not absolute 0, we refer to it as an interval scale. In obtaining this standardization sample, the authors of the Binet test had norms with which they could compare the results from any new subject. . Is it lower than the average score, or is it about the same? Obtain ΣX, or the sum of the scores: 5.15 + 8.81 + 14.76 + 10.86 + 7.86 + ... + 3.62 = 454.80 Find N, or the number of scores: N = 44 3. This chapter reviews both descriptive and inferential statistics.

Social science researchers commonly label groups in sample surveys with numbers (such as 1 ⫽ African American, 2 ⫽ white, and 3 ⫽ Mexican American). The standardization sample was increased to include 1000 people, original items were revised, and many new items were added. Properties of Scales Three important properties make scales of measurement different from one another: magnitude, equal intervals, and an absolute 0. The TAT purported to measure human needs and thus to ascertain individual differences in motivation. The formulas just presented are for computing the variance and the standard deviation of a population. Permissible Operations Level of measurement is important because it defines which mathematical operations we can apply to numerical data. In the early 1940s, J. R Guilford made the first serious attempt to use factor analytic techniques in the development of a structured personality test. .

The Thematic Apperception Test (TAT): A projective test that provided ambiguous pictures and asked subjects to make up a story. Equal Intervals The concept of equal intervals is a little more complex than that of magnitude. When calculating the percentile rank, you exclude the score of interest and count those below (in other words, Italy is not included in the count). To get ΣX 2, each individual score is squared and the values are summed. Thus, after an initial surge of interest and optimism during most of the 1920s, structured personality tests declined by the late 1930s and early 1940s.
