Frequency+distribution

=Frequency Distribution=

Frequency

 * Frequency** is how often something occurs.

Example: Mohammed played footbal on
The frequency was 2 for Saturday, 1 for Thursday, 1 for Friday and 4 for the week
 * Saturday Morning,
 * Saturday Afternoon
 * Thursday Afternoon
 * Friday morning

By counting frequencies we can make a **Frequency Distribution** table. Example:1 scores Mohammed's team scored the following goals: 1,1,3,1,2,2, 3,3,3,4,5,1,1,1 the goals can be put in frequency distribution by counting the number of times of the scores as follows:
 * Frequency distribution**
 * Score || Frequency ||
 * 1 || 6 ||
 * 2 || 2 ||
 * 3 || 4 ||
 * 4 || 1 ||
 * 5 || 5 ||

from table we can see that scoring one goal in a match occurs most frequent and and scoring 5 and 4 occured only once. Example 2 Football shoes These are the number of football shoes sold at a local sport shop for 10 days: 25,20,25,23,25,20,30,31,18,19 let find the frequency distribution of the sales:
 * Frequency distribution** is therefore about values and their frequency i.e how often how often each value occurs

It is also possible to group the values as demonstrated below in intervals of 5 Graphs are use to represent frequency distributions. The graphs can be bar graphs or pie charts.
 * shoes sold || frequency ||
 * 18 || 1 ||
 * 19 || 1 ||
 * 20 || 2 ||
 * 23 || 1 ||
 * 25 || 3 ||
 * 30 || 1 ||
 * 31 || 1 ||
 * Shoes sold || Frequency ||
 * 15 - 19 || 2 ||
 * 20 - 24 || 3 ||
 * 25 - 29 || 3 ||
 * 30 - 34 || 2 ||
