4.2 Normality test
In order to determine if all of the data collected is normally distributed, a normality test is carried out. Normal distribution is assumed for
Skewness and Kurtosis for values of variables is between -3.29 and +3.29 for sample size range between 50 to 300 (Mishra, et al., 2019).

Kurtosis

There are 6 statements that represent the independent variable, trailer were shown in Table 4.5. ‘T6’ achieve the highest mean, with 4.75,
meanwhile the lowest mean achieve is 4.69 in ‘T1’. The skewness for all statement is negative, which between -.834 to -1.490. The
kurtosis for all statement is positive range between .013 to 1.049, except for ‘T1’ which indicate -1.331. This means that the z- value for
both skewness and kurtosis are in between -3.29 and +3.29, resulting in normal distribution for trailer variable.

There are 6 statements that represent the independent variable, critic reviews were shown in Table 4.6. ‘CR1’ achieve the highest mean,
with 4.30, meanwhile the lowest mean achieve is 3.39 in ‘CR5’. The skewness for all statement is negative, which between -.232 to - 1.323,
except for ‘CR1’, which indicate positive skewness value of .607. The kurtosis for all statement is negative range between -.939 to
-1.429, except for ‘CR2’ which indicate positive kurtosis value of 2.003. This means that the z-value for both skewness and kurtosis are in
between -3.29 and +3.29, resulting in normal distribution for critic reviews variable.
