Appendix statistics in psychology & biological foundations of behavior. What does our sample look like what are the range of scores. Scores on the anxiety scale ranged from 3. 66 - 17. 7 with an average of 10. 1. The mean score on the measure of anxiety was 7. 4 in the control group and 12. 3 in the treatment group. Anxiety scores were highly correlated with neuroticism scores. We can report that in 3 ways, single number to describe the data set. Mean = average of all scores, most commonly used, Important to give measures of variability so people understand the range of your results. Measure of how widely spread the data are. Or was it just a result of chance/randomness in the numbers. Correlation coefficient (r = -1. 00 to +1. 00) How much variance in variable b is accounted for by variance in variable a. Null hypothesis- there is no difference between groups (iq, no effect of iv on dv)
