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.

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.

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.

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.

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.
