Final answer:
The three measurements of central tendency used to summarize data are the mode, median, and mean.
Step-by-step explanation:
There are three measurements of central tendency used to summarize data: mode, median, and mean.
- Mode: The mode is the most frequently occurring value in a data set. It can be a single value or there can be multiple modes if they have the same frequency.
- Median: The median is the middle value in a data set when the values are arranged in order. It is not affected by extreme values or outliers, making it useful when the data set contains such values.
- Mean: The mean is the arithmetic average of all the values in a data set. It is calculated by adding up all the values and dividing by the total number of values. The mean is sensitive to outliers and can be influenced by extreme values.
