Three worksheets designed for students to practice interpretation of p-values, writing a null hypothesis & selecting an appropriate statistical test (with a reason) and writing a conclusion based on selection of and interpretation of a critical value.

FULL ANSWERS are included in the download. Wording of answers is based on past mark schemes wherever possible. If you disagree with any of the answers, please email me at teachsecondaryscience@gmail.com and changes will be made if needed.

I use worksheet 1 and 2 in lessons, with students talking through the correct answers for revision (or they could complete the worksheet as homework on lined paper, these two worksheets don’t include answer spaces).

The third worksheet is useful as a homework task in the run-up to the A-level exams & includes answer spaces.

Worksheet 1: 10 questions
Example question = A study investigates the effect of a new antibiotic on bacterial growth. The researchers calculate a p-value of 0.03. What can the researchers conclude about the effectiveness of the antibiotic?

Worksheet 2: 8 questions
For each scenario, students must write a null hypothesis, select a statistical test and give a reason as to why that test is appropriate.

Worksheet 3: Three page worksheet consisting of 3 multi-part questions.
The main focus of this worksheet is for students to practice selecting the right critical value from part of a critical value table & then coming to a conclusion based on whether the calculated value is greater than or less than the critical value.

**PLEASE NOTE this resource DOES NOT include any questions which require students to perform calculations using statistical tests. **
