We are preparing to close this site and currently expect this to be in June 2024
but we are reviewing this timing due to the large volume of content to move and
improvements needed to make it easier to find different types of content on
Tāhūrangi.
We will update this message again shortly.

Any table that displays the frequencies of values of one or more variables in a data set.
For a whole-number variable in a data set, a table showing each value of the variable and its corresponding frequency.
For a measurement variable in a data set, a table showing a set of class intervals for the variable and the corresponding frequency for each interval.
For a category variable in a data set, a table showing each category of the variable and its corresponding frequency.
A frequency table will often have an extra column that shows the percentages that fall in each value, class interval or category.
