Plan to return to lab by 4:00.)  You must include your instructor in the sample as the first participant. Define the dependent variable on at least an ordinal scale.

C. Collect the data in as controlled a setting as possible.

D. Analyze the data using the SPSS software.  Calculate the measures of central tendency, dispersion for each group. Compute the appropriate inferential statistic. You had a between subjects design, threfore  use a t-test for independent groups. 

E. Report your method and results using APA style.  There is no lab report form for this lab. You may find this Internet resources helpful:
