10.10 The Computer Anxiety Rating Scale (CARS) measures an individual’s level of computer anxiety, on a scale from 20 (no anxiety) to 100 (highest level of anxiety). Researchers at Miami University administered CARS to 172 business students. One of the objectives of the study was to determine whether there is a difference in the level of computer anxiety experienced by female and male business students. They found the following: SELF Test a = 0.05. 3.75 0.65 1.92 0.60 1.53 4.23 0.08 1.48 1.65 0.72 7.55 3.75 0.10 1.10 0.60 0.52 3.30 2.10 0.58 4.02 1.02 0.53 0.93 1.60 0.80 1.05 6.32 3.93 5.45 0.97 1.48 1.75 0.78 2.85 0.52 1.60 4.15 3.97 1.48 3.10 Phone Males Females X 40.26 36.85 S 13.35 9.42 n 100 72 Source: Data extracted from T.
