Understanding Mean, Median, Mode and Range S4
In this DfE Standards Unit resource, students learn to understand the terms: mean, median, mode, range and explore the relationships between these measures and their relationship to the shape of a distribution. Students will have met the terms mean, median, mode and
range but they may not have a clear understanding of their meaning and the relationships between them. One purpose of this session is to expose and discuss any misconceptions. (GCSE Grades A - F)
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment.
Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date.
Since that time there have been significant changes in the rules and guidance affecting laboratory practical work.

Review
Activity time: 2 or 3 lessons
Level / prior knowledge: KS4 Higher/Mean/Mode/Median/Range
Subject / curriculum links / skills: Data Handling/Displaying data in Physics/Engineering/Technology
Preparation time: Printing the recording worksheet
Extra resources: Ensure a .swf file (flash) does work on the school computer before using it. Put this on your memory stick and then double click the file on the actual computer to be used. This simple, but necessary, test is required.
Commentary:
I used this for a full activity for one lesson. The key was to move from a simple line of numbers to a frequency table and by using the file interactively it seemed to engage the pupils more than previous lessons.
The frequency table and bar chart change when the raw data is changed and the pupils saw how each change affected the result. The main objective was gained as they moved to frequency tables with ease and hence it impressed me. The bar chart was easy to teach as well as this obviously made an impression.
The pdf was used to produce a recording sheet so my pupils recorded the raw scores. I hid the results and they then worked out the frequency table and bar chart. I then revealed the results so they could mark on their own. After around 3 attempts all succeeded and hence it improved my lesson.
