Step 1

The mean is the sum of all the data points divided by the number of data points. In this case, we have 12 data points and their sum is 699. So, the mean is calculated as follows: \[ \text{Mean} = \frac{\text{Sum of all data points}}{\text{Number of data points}} = Show more…

Key Concepts

Mean

The mean is the arithmetic average of a set of numbers, calculated by summing all the data values and then dividing by the total count. It provides a measure of central tendency that takes into account every value in the dataset, making it sensitive to extreme values or outliers.

Median

The median is the middle number in an ordered dataset. When the data are arranged in ascending or descending order, the median divides the dataset into two halves, providing a robust measure of central tendency that is less influenced by outliers compared to the mean.

Mode

The mode is the value that appears most frequently in a dataset. It represents the most common observation and can be particularly useful in identifying the most typical value in a frequency distribution, even in data that may not necessarily have a symmetric distribution.
