For data set 1, mode was the measure of central tendency used. The mode of class 01/02 was calculated as 2. This means that the occupation that the answer, "2" refers to is the most common occupation that the students of that class held prior to entering the university or during summer…
For class 02/03, the mean of 48.5 means that most of the scores falls somewhere near 48.5.
Lastly, for Data Set 3, the median was measured. Both of the classes had a median of 3. This means that the rating of 3 is the middle score when the scores are arranged from lowest to highest or vice versa.
Range was the measure of variability for Data Set 1. Since both classes had a highest mark of 5 and a lowest mark of 1, they had the same value for the range. This means that the jobs that the students in the classes being studied took jobs that range from those signified by 1 until 5.
For Data Set 2, the standard deviation was measured. For class 01/02, this was calculated to be 20.85 while for class 02/03, it was 21.17. Since Class 01/02 has a smaller S.D. than Class 02/03, this means that there is more variation in scores for the latter. Although both classes had scores that were very distinct, the lesser S.D. signifies less variation.
In Data Set 3, the semi-inter quartile was measured. The results of the measure mean that the values of Class 01/02 are from the X-axis than those of Class 02/03. The value of the SIQ refers to half the range, between Q1 and Q3.
The pie graphs for data set 1 makes evident that in class 01/02, there is no individual who took up a pre-university or summer job as a skilled or semi-skilled worker. ...
