Frequency tables are a way of laying out data to show the number of items there are in different categories. From frequency tables you can see what are the most and least frequent categories, and easily calculate mean, mode and range for a data set. They are also used as a source to generate more graphical representations such as bar charts, pie charts, etc.
Frequency tables make it easy to find the mode, median and range for a data set. The mean takes a little more work.
The mode is the most frequent value in a data set. To find the mode from a frequency table, find the item or category with the highest frequency.
The median is the middle value in an ordered data set. To find the position of the median value in a frequency table, add up all the frequencies in all the categories, add one more and then divide by two. This will identify the position of the median value of the data set. If the result is a decimal, the position of the median value is halfway between two frequencies.
The range is the spread of values in a data set. To find the range of data from a frequency table, take away the smallest value from the largest value.
The mean is the average value of a data set. To find the mean from a frequency table, do the following. Multiply each category by its frequency. Add these values to get the total value from all the categories. Add all the frequencies together to get the total frequencies. Now divide the total value by the total frequencies to get the mean.
In this topic you are asked to derive the mean, mode, median or range for a series of frequency tables.
There are 8 question/answer pairs in the lessons for this topic, and an additional 8 question/answer pairs in all the games and tests.
With our Four in a row math game you will be practicing the topic "Mean mode median range" from 8th grade / Statistics / Discrete data / Discrete data. The math in this game consists of 16 questions that ask you to calculate the mean, mode, median or range for the given frequency tables to 2 d.p..
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
