Grouped Frequency Table Worksheet. Data may be discrete or continuous. This is a worksheet i made for my year 11s to practice finding the mean from grouped data.
150 h leq 160 150 h 160. The grouped frequency table can be used to find the average of a set of numbers. A frequency table is a visual that displays relative frequencies of the data points.
To construct a frequency table we just list all of the data that appears in the set in ascending order vertically.
Other types of frequency table. A frequency table shows how often how frequently each number appears in a list of numbers. If we have collected a lot of data we might display it in a frequency table we need to be able to construct a frequency table and know how to interpret and use one to solve problems such as calculating the mean median mode and range of the data.
