| 2. How is the median calculated when there is an even number of data points? | |
Ans. When there is an even number of data points, the median is calculated by taking the average of the two middle values. Add the two middle values and divide the sum by 2 to find the median.

Ans. The mode is a statistical measure that represents the value or values that occur most frequently in a data set. In other words, it is the data point(s) with the highest frequency or count.
| 4. How is the mode determined in a data set? | |
Ans. To determine the mode in a data set, you need to identify the value or values with the highest frequency. The mode can be a single value, multiple values, or even nonexistent if no value repeats more than once.
| 5. Can a data set have more than one mode? | |
Ans. Yes, a data set can have more than one mode. If there are multiple values with the same highest frequency, all of them are considered modes. This type of distribution is known as "multimodal."
