A Researcher Is Using a Standardized Test of AP (Anger

question 35

Short Answer

A researcher is using a standardized test of AP (Anger Potential) and selects 16 subjects to take the test which has a population mean of 20 and an SD of 6.00. The test scores were then converted into both z scores and T scores (See Chapter 5). The scores are as follows: $$\begin{array} { c c r c } \text { Subj\# } & \text { X (raw scores) z } && \text { T } \\1 & 5 & - 2.50 & 25.00 \\2 & 14 & - 1.00 & 40.00 \\3 & 14 & - 1.00 & 40.30 \\4 & 17 & - 0.50 & 45.00 \\5 & 17 & - 0.50 & 45.00 \\6 & 17 & - 0.50 & 45.00 \\7 & 20 & 0.00 & 50.00 \\8 & 20 & 0.00 & 50.00 \\9 & 20 & 0.00 & 50.00 \\10 & 20 & 0.00 & 50.00 \\11 & 23 & 0.50 & 55.00 \\12 & 23 & 0.50 & 55.00 \\13 & 23 & 0.50 & 55.00 \\14 & 26 & 1.00 & 60.00 \\15 & 26 & 1.00 & 60.00 \\16 & 35 & 2.50 & 75.00\end{array}$$
