Task 

Use Minitab to analyse the coursework dataset, completing all analysis tasks and writing up your results and conclusions for each task (word limit: 2000 words). The Minitab dataset that you are required to analyse is available under the ‘Assessments & Support Materials’ section on Moodle.

Learning outcomes 

LO1 Summarise and present data using the mean, median, standard deviation, histograms, box plots, and bar charts.
LO2 Analyse and interpret data using t-tests, ANOVA, non-parametric tests, Chi-squared tests, correlation, and linear regression.

Submission Instructions 

Your work must be submitted to the submission box by 4pm on 2nd December 2025.
You must submit your work as a PDF.
The filename should be your student ID number, e.g. UP1234567.
Your name should not appear anywhere on or within your submission.
You should also upload your Minitab Project File with your submission.

Coursework Dataset 

Note that there are several versions of the coursework dataset, but only one dataset will be visible on your Moodle: you must analyse your dataset. Using a dataset from another student’s Moodle may result in a plagiarism investigation.

DATA

The dataset contains observations from a sample of soil blocks. Each block has been reinforced with a type of organic fibre. A water absorption test has been performed on each block.
There are four variables: Fibre type
Water absorption (%)
Soil type
Fibre content (% by volume)

Part 1

(a) Present appropriate numerical and graphical summaries for each of the variables. Comment on their distributions, and (where appropriate) the presence or absence of any outliers.
(b) Report the 95% confidence interval for the mean water absorption, then use an appropriate hypothesis test to determine whether there is any evidence that the mean water absorption is not equal to 20%. You may assume that the underlying distribution of water absorption is Normal.
(c) Evaluate whether the data is consistent with the claim that the median fibre content is 1.0%. Justify your choice of method.

Part 2

Use appropriate analyses to investigate the relationships between each of the following pairs of variables.
(a) Water absorption and fibre type.
You may assume that the underlying distribution of water absorption is Normal.
(b) Fibre type and soil type.
(c) Water absorption and soil type.
You may assume that the underlying distribution of water absorption is Normal.
(d) Water absorption and fibre content.

Part 3

(a) Determine whether the relationship between water absorption and fibre content varies by fibre type.
(b) Develop a multivariable linear regression model for water absorption, with fibre type, soil type and fibre content as potential predictors. Include all steps of your modelling process and fully justify your choice of final model.
(c) For your final model, explain the effect of each predictor on the outcome variable by interpreting each of the regression coefficients and their p-values.
