Lesson Planning Validity and Reliability of the Test
2 Analyzing the normality distribution with Kolmogorov-Smirnov test.
Comparing the asymp.sig 0.05, the null hypothesis is not rejected and alternative hypothesis is rejected, and the distribution of data is normal.
Hence, if the asymp.sig 0.05, the null hypothesis is rejected and alternative hypothesis is not rejected, and it means the data is not normally
distributed.

The normality test above used Kolmogorov-Smirnov critical points table in determining the ttable. According to the consideration of n=45 and significance
level 0.05, the ttable of this normality test was 0.198. Furthermore, table showed that the t value of experimental class was 0.115 and the tvalue of controlled. Class
was 0.128. The values were smaller than ttable, in other words, tvalue ttable 0.1150.198 for experimental class, and 0.1280.198 for controlled class.
Therefore, Ho was accepted and Hi was rejected. It meant that the distribution of the data was normal. Also, the significance of experimental class was 0.184 and
the significance of controlled class was 0.070. The result shown that the significance of both classes are above 0.05. Therefore, the distribution of posttest
score was normal.

The normality test in table used Kolmogorov-Smirnov critical points table in determining the ttable. According to the consideration of n=45 and significance
level 0.05, the ttable of this normality test was 0.198. Furthermore, table 4.3 shown that the tvalue of experimental class was 0.102 and the tvalue of controlled
class was 0.083. The values were smaller than ttable, in other words, tvalue ttable 0.1020.198 for experimental class, and 0.0830.198 for controlled
class. Therefore, Ho was accepted and Hi was rejected. It meant that the distribution of the data was normal. Also, the significance of experimental class
was 0.200 and the significance of controlled class was 0.200. The result show that the significance of both classes was above 0.05. Therefore, the distribution of
post-test score was normal.
