Q:

What does "modal" mean in mathematics?

A:

Quick Answer

Modal value refers to the mode in mathematics, which is the most common number in a set of data. For example, in the data set 1, 2, 2, 3, the modal value is 2, because it is the most common number in the set.

Full Answer

The mode is one of the most common ways to describe a set of data. Often, when large sets of data are being analyzed, it is useful to calculate the mean, mode and median to quickly gain insight into how the numbers are distributed. The mean is the average of the data set, while the median is the middle number when ordered from smallest to largest.

  • Q:

    What does mean, median and mode mean?

    A:

    According to Oxford University's Medical Sciences Division, the mean is the average value of a group of numbers, the median is the middle value in an ordered list of values and the mode is the most common number that appears in that numerical group or list. So, for a list of values such as 2, 3, 3, 6, 7, 8, 11, the mean (or average) would be 5.71, the median (or middle value) would be 6 and the mode (or most common value) would be 3.

  • Q:

    Why do we use standard deviation?

    A:

    Standard deviation is a measure of the variation or diversity of scores in a set of data. It is used to determine how much data varies from the average of a population. The larger the deviation, the more spread out the data set. Standard deviation is represented by the Greek letter sigma.

  • Q:

    How do you find midrange?

    A:

    The midrange is the average of the maximum and minimum values of a set of data. This measure of center is not as common as the mode, mean or median.
