This question provides a list of data to the student. They are asked to find the mean, median, mode and range.

Statistics and probability. Two questions: using LSD and Tukey yardsticks.

Given two distributions, calculate the measures of average and spread and make some decisions based on the results.

Spearman rank correlation calculated. 8 paired observations.

One-way ANOVA example

Given a table of data, calculate the mean, mode and median, and complete a frequency table.

This question assesses the students ability to find the expected number of times an event occurs given the probability of the event occurring for a single trial and the total number of trials.

Calculate relative frequencies in a variety of scenarios.

Questions on the subtleties and pitfalls of methods of data collection.

Questions on presenting data in charts or tables.

6 questions on standard statistical distributions.

Binomial, Poisson, Normal, Uniform, Exponential.

A multiple linear regression model of the form:

\[Y=\beta_0+\beta_1X_1+ \beta_2X_2+\beta_3X_3+\beta_4X_4+\epsilon \]

is fitted to some data in Minitab which generates a table showing estimates of the parameters with associated $p$-values. Determine which variable to exclude first.
