Part A . SPSS Activity

Exploratory Data Analysis

Data was collected for students involved in a pilot research carried out to determine if 5th grade girls do better in small class sizes while boys excel in larger classes

Bar graphs were formulated to give a clear visual representation of the data and show the relationship between the two genders in the three situations of classroom sizes (Walpole , 1987

Bar Graph for the Genders in the three classroom sizes

The data was analyzed and the exploratory data

analysis results were formulated as follows

Gender Classroom size Math Score

Mean Standard Deviation

Female 10 or less 93 .8 3 .7

11 to 19 88 .5 3 .9

20 and above 79 .2 4 .4

Male 10 or less 92 .7 3 .2

11 to 19 89 .7 2 .1

20 and above 91 .2 3 .9

The results showed that the group with the highest mean score in Math was the one for female in a classroom of less than 10 students while the females in a class of greater than 20 students had the overall smallest Math score . However , there was no much difference in mean Math Score between the male students in the class with a small size of less than 10 and those in a class of greater than 20 students

The results therefore implied that female students in small classes had a better score in Math than those in large class . However , there is no...
