Ideal Self‚ and Economic Incentive have a normal population distribution (p-value < 5%)‚ and only Direct Contact shows no deviation from normal distribution (p-value > 5%) (Field‚ 2013). However‚ the number of the sample (N=115) is large enough to consider it a non-issue. The Shapiro-Wilk normality test also rejects that the TOEIC score has a normal distribution since the p-value is .000 which is less than 5 percent. For a distribution to be considered normal‚ p-value has to be greater than 5% (Field

A number of tests may be appropriate in this situation‚ i.e. Parametric test and Non-parametric test. Parametric

Notice that Chebyshev inequality provides a bound for almost every distribution. It says that if X is picked from the population which has mean θ and standard deviation s‚ the probability that any one realization of x is [pic]farther from θ is less than [pic] .
