Mean
- The mean is a measure of central tendency that takes into account all the data points in a dataset.
- It is calculated by summing up all the values in the dataset and then dividing the sum by the total number of values.
- The mean represents the average value of the data and provides a measure of the "typical" value in the dataset.

Median
- The median is another measure of central tendency that represents the middle value in a dataset.
- To calculate the median, the data points are first arranged in ascending or descending order.
- If the dataset has an odd number of values, the median is the middle value.
- If the dataset has an even number of values, the median is the average of the two middle values.
- Unlike the mean, the median does not take into account all the data points in the dataset. It only considers the middle values.

Mode
- The mode is the value that appears most frequently in a dataset.
- It can be used to identify the most common value or values in a dataset.
- The mode may not always exist in a dataset, as there can be cases where no value appears more than once.
- Like the median, the mode does not consider all the data points in the dataset. It only focuses on the most frequent values.

Conclusion
- Among the three measures of central tendency, only the mean takes into account all the data points in a dataset.
- The mean provides a comprehensive representation of the dataset by considering each value and their contribution to the overall average.
- However, it is important to note that the mean can be influenced by outliers or extreme values in the dataset, which may not be representative of the entire data.
