Analyzing Data Involving Sex Distribution, Age, and Ethnicity

(1) Determine 10 variables of interest and determine the appropriate scale of measurement for each variable using the excel sheet attached.

(2) Choose and compute the appropriate descriptive statistics to describe characteristics of the sample under study (such as sex distribution, age, and ethnicity) and the anxiety reported by the sample at pretreatment. Included one graph, a measure of central tendency, and a measure of variability. Report the findings in the APA format and write a brief paragraph describing your findings

(3) Using the appropriate descriptive statistics from #2 and assuming that the sample statistics you computed are exactly equivalent to the corresponding population parameters, identify:

What score on the pretreatment Revised Children's Manifest Anxiety Scales (RCMAS) would correspond to an extremely high score? For example, would you expect less than 5 percent of the population to score this high?

What score on the pretreatment RCMAS would correspond to an extremely low score? For example, would you expect less than five percent of the population to score this low?

In addition, complete the table indicating the z-scores corresponding to each of the participants whose score is given. Write a brief paragraph interpreting these z-scores.
