MA32-02
This lesson is coming soon.
In this lesson
Identify the modal class of a grouped frequency distribution as the group with the highest frequency.
What it covers
- Identify the modal class as the group/interval with the highest frequency in a grouped frequency table
Key words
For: Cambridge IGCSE 0580, Edexcel IGCSE 4MA1, OCR GCSE J560, AQA GCSE 8300, Edexcel GCSE 1MA1, Eduqas GCSE C300
On the specification
| Board | Spec | Statement |
|---|---|---|
| Cambridge IGCSE 0580 | E9.3 | Calculate the mean, median, mode, quartiles, range and interquartile range for individual data and distinguish between the purposes for which these are used. |
| Edexcel IGCSE 4MA1 | F6.2D | Identify the modal class for grouped data |
| OCR GCSE J560 | 12.03a | Calculate the mean, mode, median and range for ungrouped data. Find the modal class, and calculate estimates of the range, mean and median for grouped data, and understand why they are estimates. Describe a population using statistics. Make simple comparisons. Compare data sets using `like for like' summary values. Understand the advantages and disadvantages of summary values. |
| AQA GCSE 8300 | S4 | • including box plots |
| Edexcel GCSE 1MA1 | S4 | interpret, analyse and compare the distributions of data sets from univariate empirical distributions through: • appropriate graphical representation involving discrete, continuous and grouped data • appropriate measures of central tendency (median, mean, mode and modal class) and spread (range, including consideration of outliers) |
| Eduqas GCSE C300 | FS4 | Interpret, analyse and compare the distributions of data sets from univariate empirical distributions through: appropriate graphical representation involving discrete, continuous and grouped data; appropriate measures of central tendency (median, mean, mode and modal class) and spread (range, including consideration of outlier) |
| Eduqas GCSE C300 | HS5 | Interpret, analyse and compare the distributions of data sets from univariate empirical distributions through: appropriate graphical representation involving discrete, continuous and grouped data, including box plots; appropriate measures of central tendency (median, mean, mode and modal class) and spread (range, including consideration of outliers, quartiles and inter-quartile range) |
For teachers
This GCSE Maths lesson teaches finding the modal class. By the end, students should be able to identify the modal class of a grouped frequency distribution as the group with the highest frequency. It works through one worked example and the mistakes examiners report.
