The Mean M is the average point X which is obtained by counting the sum of the score
∑X then it is divided by the number of subjects N. The formula is:
M = the average points
∑X = the sum of the score
N = the number of subject
The estimation of the participants’ opinions on the designed materials used five points of agreement and disagreement namely:
1: if the participants strongly disagree with the statement 2: if the participants disagree with the statement
3: if the participants neither agree nor disagree with the statement 4: if the participants agree with the statement
5: if the participants strongly agree with the statement The data were presented in the form of table in which the participants opinions,
statements, and the mean. Statements

The data showed whether the designed materials were good, acceptable or not. 1.01 – 2.50 = poorly design and not acceptable
2.51 – 3.50 = good design but needs revisions 3.51 – 5.00 = good design and acceptable

The design materials were good and acceptable if the mean was more than 75. The design materials were good but needed revisions if the mean was 50 up to
75. The design materials were poor and not acceptable if the mean was below 50.
The researcher made all list about the participants comments and suggestions. The researcher revised the designed materials in order to make the better form.
