1. The Normality Test
The sample is in normal distribution if L
o
L obtained is lower than L
t
L table at the level of significance
α = 0.05 on Lilliefors. The formula used in this testing is:
晐 ∑ 莐
∑ 莐 n
n 1 莐 莐
晐 a.
Column A

. In this column, that contains 30 students who were taught by using Note-
Taking Pairs technique n = 30, the highest value of Fz
i
– sz
i
or L
o
is 0.1340. L
t
at the level of significance α = 0.05 is 0.161. Because L
o
is lower than L
t
0.1340 0.161, it can be concluded that the sample is in normal distribution.
b. Column A

. In this column, that contains 30 students who were taught by using DR-TA
technique n = 30, the highest value of Fz

is 0.0879. L
t
at the level of significance α = 0.05 is 0.161. Because L
o
is lower than L
t
0.0879 0.161, it can be concluded that the sample is in normal distribution.
c. Row B

. In this row, that contains 30 students having high linguistic intelligence n =
30, the highest value of Fz

– sz
i
or L
o
is 0.1562. L
t
at the level of significance α = 0.05 is 0.161. Because L
o
is lower than L
t
0.1562 0.161, it can be concluded that the sample is in normal distribution.

is 0.1550. L
t
at the level of significance α = 0.05 is 0.161. Because L

is lower than L
t
0.1550 0.161, it can be concluded that the sample is in normal distribution.
