Test scores have to be organized first before they

can be subjected to statistical analysis.

Through the organizational of test scores, teachers can discover existing patterns. This chapter

centers on the following ways of organizing test

scores: ordering, ranking, and the use of frequency,

distribution and the stem –and-leaf plot.

Ordering refers to the numerical arrangement of numerical observation s or measurements (Gordon &

Gordon, 1994). There are two ways by which test scores can be numerically arranged.: (1)

ascending order; and (2) descending order.

ORGANIZING TEST SCORES BY ORDERING

•ASCENDING ORDER – arranged from lowest to

highest

•DESCENDING ORDER – arranged from highest to

lowest

ORGANIZING TEST SCORES BY RANKING

Ranking is another way by which test scores can be organized.

According to Calderon and Gonzales, it is a process of

determining the relative position of scores, measures or value based on magnitude, worth,

quality or importance. To rank test scores, the following steps

should be observed.

1.Arrange the scores from highest to lowest.

2.Assign serial numbers for each score. The last serial number has to be correspond to the total number of scores, arranged in descending

order.

3.Assign the rank of one to the highest score and the lowest rank to the lowest score. Thus if there are 10 scores, the lowest rank is 10.

4.In case there are ties, get the average of the serial numbers of the tied scores. This can be done based on the following formula:

In case there are ties, get the average of the serial numbers of the tied scores. This can be done based on the following formula:

Where:R = RankSN1 = Serial Number of the ScoreSN2= Serial number of the second scoreSN3 = Other serial numberNTS= Number of the tied scores
