1: Complete the following sentence: A small standard deviation (relative to the value of the mean itself) (Hint: The standard deviation is a measure of the dispersion or spread of data around the mean.)
A. Indicates that the data points are distant from the mean.
B. Indicates that the mean is a poor fit of the data.
C. Indicates that data points are close to the mean (i.e. the mean is a good fit of the data).
D. Indicates that you should analyse your data with a non-parametric test.
2: Complete the following sentence: A large standard deviation (relative to the value of the mean itself) (Hint: The standard deviation is a measure of the dispersion or spread of data around the mean.)
A. Indicates that the data points are distant from the mean (i.e. the mean is a poor fit of the data).
B. Indicates that the data points are close to the mean.
C. Indicates that the mean is a good fit of the data.
D. Indicates that you should analyse your data with a parametric test.
3: Which of the following is true about a 95% confidence interval of the mean:
A. 95 out of 100 sample means will fall within the limits of the confidence interval.
B. 95 out of 100 confidence intervals will contain the population mean.
C. 95% of population means will fall within the limits of the confidence interval.

4: ‘Children can learn a second language differently before the age of 7 than after.’ Is this statement:
A. A non-scientific statement
B. A one-tailed hypothesis
C. A null hypothesis
D. A two-tailed hypothesis
5: What does the assumption of independence mean?
A. This assumption means that none of your independent variables are correlated.
B. This assumption means that the errors in your model are not related to each other.
C. This assumption means that you must use an independent design rather than a repeated-measures design.
