What Mean is
Mean is a measure of central tendency that is used to measure the average of a given set of data. It is also known as the arithmetic mean, because it is calculated by adding together all of the values in a dataset and then dividing by the number of values in the dataset.
Steps for Calculating Mean:
-
Gather the data for which you want to calculate the mean.
-
Add all the values in the data set together.
-
Divide the sum of all the values in the data set by the number of values in the data set.
-
The result is the mean of the data set.
Examples
- The mean is used to measure the central tendency of a dataset, which is the average value of all the data points within a dataset.
- The mean can be used to compare two data sets by calculating the difference between their means.
- The mean can be used to compare distributions by calculating the standard deviation from the mean.
- The mean can be used to identify outliers in a dataset by calculating the distance from the mean for each data point.
- The mean can be used to identify clusters in a dataset by calculating the average distance from the mean for each cluster.
