Quiz 2

What does skewness measure in a dataset?

• The flatness or peakedness of the data distribution

• The center point of the data distribution

• The asymmetry of the data distribution

• The variability within the data

TRUE OR FALSE:

We consider using the test of normality if the dataset contains more than 100 respondents

• TRUE

• FALSE

TRUE OR FALSE:

Non-Parametric Test is used when the data does not follow a normal distribution curve

• TRUE

• FALSE

If the p-value in a Shapiro-Wilk test is less than 0.05, what does this indicate?

• The data does not deviate from normality.

• The data is normally distributed

• The data deviates from normality

• The data distribution is mesokurtic

A dataset is described as leptokurtic when:

• The data is negatively skewed

• The data distribution has a higher peak compared to normal

• The data distribution is flatter compared to normal

• The data is positively skewed

The Wilcoxon Rank Sum Test is used to:

• Test the difference between two paired samples

• Test the difference between more than two independent samples

• Test the difference between two independent samples

• Test whether a dataset follows a normal distribution

The Kruskal-Wallis Test is used to:

• Assess the variance within a single sample

• Compare the means of two related groups

• Compare the medians of more than two independent groups

• Test the correlation between two variables

What is the non-parametric counterpart of One-way ANOVA?

What is the non-parametric counterpart of Dependent Sample T-test?

• Shapiro-Wilk Test

• Mann-Whitney U Test

• Kruskal-Wallis Test

• Wilcoxon Rank Sum Test

What is the non-parametric counterpart of Independent Sample T-test?

• Wilcoxon Rank Sum Test

• Mann-Whitney U Test

• Shapiro-Wilk Test
