From the total number of students of the seventh semester, only 73 students who participated to fill the questionnaire of personality test. The other 25 students belong to the other personalities; they are neither the sanguine students nor the phlegmatic students.

2. Data Analysis

To begin the data analysis, first step is finding the average of the sanguine and phlegmatic students. The way to find the average of the sanguine and phlegmatic students’ score is by the following calculation. The average in statistics is known by mean M. The pattern of Mean is ∑ Description: : t he total of students’ score : a number of students This pattern is to find Mean from single data of which scores are more than one frequency; whether they are for some data or whole of them. The following is the calculation for x 1 or the sanguine students. ∑ = 76.04 After having the first Mean, and the next step is forward to the second Mean. It is for the phlegmatic students. The calculation is as follows: ∑ = 75.17 Next step is finding the Deviation Standard of the sanguine and the phlegmatic students. Deviation Standard of sanguine students is as follows: S = √ ∑ = √ = √ = √ = 4.01 Deviation Standard of phlegmatic students is as follows: S = √ ∑ = √ = √ = √ = 1.89 The calculation and the results of the mean and deviation standard were explained on the following tables.
