1. Normality Test

Normality test is done towards two classes; those are experimental class and control class. Normality test is used to know whether the data from both sample groups which is examined comes from the population of normally distributed or not.

2. Homogeneity Test

After normality test gives indication that data is distributed normally, so it needs to do homogeneity test. Homogeneity Test is used to know the similarity of the two conditions or population.

3. Hypothesis Test

For The Hypothesis Test, the researcher uses T-Test to find out whether there is the differences between two variables in this study. After gaining the t-value, the researcher compares T -value and T- table . The formula of t-test is t o = M 1 : Mean of post-test of Experiment Class M 2 : Mean of post-test of Controlled Class SE M 1 : Standard Error of Experiment Class SE M 2 : Standard Error of Controlled Class Testing hypothesis uses criteria with significance degree 0.05. The conclusion is gained as follows: If t -value t -table , the H a is accepted. If t -value t -table , the H a is rejected or H o is accepted. H a : There is an effectiveness of Indirect Feedback technique on the students’‎achievement‎in‎writing of procedure text. H o : There is no effectiveness of Indirect Feedback technique on the students’‎achievement‎in‎writing of procedure text.
