This activity is designed to enable students to appreciate that the chi-squared test can only be carried out using frequencies. This spreadsheet offers students the chance to play with percentages and other kinds of data to develop the understanding that the chi-squared test cannot be used with this data.

In this activity students explore a spreadsheet which generates a chi-squared distribution with a specific degree of freedom. Students explore the differences in the distribution generated as the degree of freedom varies between 1 and 8. Students are required to find the mean and variance of a distribution with v...

During the statistics course, students will meet a range of different methods of hypothesis testing, all slightly different. The aim of this matching exercise is for students to create a table giving a variety of examples of situations in which a test may take place, the type of test which should be used in each...

Provided by the Advisory Committee on Mathematics Education (ACME), this resource was written in 2002. It includes recommendations on the steps to be taken, at that time, to raise the quality of mathematical provision in schools. Concerns regarding the poor uptake of students continuing to study mathematics at Post...

The activities in this workbook are designed to help students understand the Normal distribution, the student's t-distribution, the Chi-squared distribution, the F-distribution, the Exponential distribution, the Beta distribution, the Gamma distribution and the Weibull distribution.

For each distribution...

Students explore the difference between continuous and mass production, noting that there are many similarities but mass production has a large finite number of products made (which is subject to change) and continuous production whilst not infinite does not have a preplanned production size and is subject the...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Describe common sexually transmitted infections in humans.
• Identify methods of contraception that can be used to during human sexual intercourse to prevent the transmission of...

Work done in this Nuffield 13 - 16 module followed from the B units called ‘Breathing and circulation’ and ‘Food and digestion’, also from the S unit ‘Circuits’. This D unit provided enough material for eight double periods during a Further Science course and built on...

This STEMNET resource describes the background and career of STEM Ambassador Vicki Hodges, an Attitude and Orbit Control Systems engineer working on a project to develop an unmanned spacecraft.

Having joined the Astrium graduate scheme, Vicki has moved around the company and gained experience in a variety of...

This Nuffield Pathways Through Science module began with the study sound waves and vibrations including how the ear works and the properties of ultrasound. This led on to activities related to how sound vibrations are captured, recorded, and produced. The final group of...

Powered by Crumble, Control freak resources are all about engagement, enjoyment and learning at the same time. S...

This is one of a series of focused units, from the Association for Science Education and the Design and Technology Association, to introduce students to important technologies and their applications. This unit features control systems and their applications to...

A Year 11 module from the Salters Key Stage Four double award science course. This module introduces ideas about how living organisms control their internal environment and respond to changes in their external environment. Students are reminded that few living things...

One of the trial units from the Nuffield Primary Solutions in Design and Technology. Children investigate the movement of vehicles, from those they may have made, to commercial toys; from push along toys to remote controlled toys and a computer-controlled floor robot. The control of the floor robot will be the...
