Frequency/ frequency tables
One way of presenting data is by using a frequency distribution table. Frequency is the number of times a result or piece of data occurs. The frequency distribution table consists of three columns: score, tally and frequency.
Outliers
The numbers away from the centre spread.
Mean
The mean of a set of data is another name for the average. It is calculated by adding all the data values, and dividing by the number of values in the set of data.
Median
The median is the middle value of the data when the values are arranged in numerical order.
Mode
The mode of a set of data is the most frequently occurring value.
Range
The range of a set of values is the difference between the highest and lowest values.
