1. Twenty-one heavy smokers were put on a treadmill at the fastest setting. The time in seconds was measured until they fell off from exhaustion: 18, 16, 18, 24, 23, 22, 22, 23, 26, 29, 32, 34, 34, 36, 36, 43, 42, 49, 46, 46, 57. Compute using SPSS (state the steps you used and indicate your outputs)

   1. the mode,

   2. median,

   3. mean,

   4. range and

   5. interquartile range

2. you have been given the following scale data (test scores)

scores 100, 109, 114, 118, 125, 135, 135, 138, 139, 140

you must set up a dataset in SPSS and then transform the data using the compute Variable and arithmetic functions to calculate new variables giving the log and the square root of the original test score.
