What is a dependent variable  ?

• Variable that is affected by the change

• Variable that is changed  

• Variable that is not tested  

• Variable that doesn’t change at all  

What graph is the best representation of medians?  

• Bar Chart

• Box Plot

• Histogram

• Pie Chart

What does df stand for

• dependent variable

• dependent frequency

• descriptive frequency

• degree of freedom

What is the first step in the hypothesis testing

• Set the criterion  

• Compute the statistic  

• State the hypothesis  

• Make a decision  

What is used during the analysis stage

• Normality

• Equal Variances

• Both

• Neither

What is the assumption that the amount of variability in each of the two groups is equal  

• T-test

• Average Value

• Shapiro Wilk’s test  

• Homogeneity of variance  

If P value is less than 0.05 data is not normally distributed

• True

• False

If P value is greater than 0.05 data is normally distributed but we can’t use the t-test  

• True

• False

If the interval does not contain 0 than we reject the  Ho

• True

• False

What is a measure of how different two groups are from one another  

• Small effect

• Medium effect

• Large effect

• Effect size
