Sample of size $24$ is given in a table. Find sample mean, sample standard deviation, sample median and the interquartile range.

Calculate and work with measures of central tendency such as mean, median and mode, and measures of spread such as range and standard deviation.

Calculate and work with measures of central tendency such as mean, median and mode, and measures of spread such as range and standard deviation.

Two ordered data sets, each with 10 numbers. Find the sample standard deviation for each and for their sum.

Compute a 95% confidence interval for the population mean given a small sample, and compare it with a confidence interval for a different population.

Provided with information on a sample with sample mean and known population variance, use the z test to either accept or reject a given null hypothesis.

Three questions on parametric hypothesis testing and confidence intervals, aimed at psychology students.

Provided with information on a sample with sample mean and standard deviation, but no information on the population variance, use the t test to either accept or reject a given null hypothesis.

Provided with information on a sample with sample mean and standard deviation, but no information on the population variance, use the t test to either accept or reject a given null hypothesis.
