The researcher calculated the data based on the data based on the step of the test. The formulation as followed:
1. Determining mean of variable X Experimental Class, with formula: =
=
= 22.56
2. Determining mean of variable Y Control Class, with formula: =
= = 4.87
3. Determining standard of deviation of variable X, with formula:
√
=
√
=
√
= 7.89
4. Determining standard of deviation of variable Y, with formula:
√
=
√
=
√
= 6.75
5. Determining standard error of mean variable X, with formula:
√
=
√
= = 1.2484
6. Determining standard error of mean variable Y, with formula:
√
=
√
= = 1.0680
7. Determining standard error of different mean variable X and mean of variable Y, with formula:
√ =
√
=
√ =
√ = 1.51
8. Determining with formula:
= =
= = 11.715
9. Determining degree of freedom df, with formula: df =
– 2 = 41 + 41 – 2 = 82 -2
= 80
