Tally chart
A table used to record values for a variable in a data set, by hand, often as the values are collected. One tally mark is used for each occurrence of a value. Tally marks are usually grouped in sets of five, to aid the counting of the frequency for each value.
A tally chart provides an immediate visual form of the distribution.
Example
The number of days in a week that rain fell in Grey Lynn, Auckland, from Monday 2 January 2006 to Sunday 31 December 2006 is recorded in the tally chart below.
The tally chart can then be re-drawn as the following frequency table.
| Number of days with rain | Number of weeks |
|---|---|
| 0 1 2 3 4 5 6 7 |
2 5 5 5 19 6 6 4 |
| Total | 52 |
