FAQs on Median & Mode- 4 Video Lecture - Statistics for Economics - Class XI - Commerce
| 1. What is the median and mode in statistics? |  |
Ans. The median in statistics is the middle value in a set of data when it is arranged in ascending or descending order. It is the value that separates the higher half from the lower half of the data. The mode, on the other hand, is the value that appears most frequently in a set of data.
| 2. How do you calculate the median of a set of numbers? | |
Ans. To calculate the median, first, arrange the set of numbers in ascending or descending order. If the set has an odd number of values, then the median is the middle value. If the set has an even number of values, then the median is the average of the two middle values.
| 3. What does the mode represent in statistics? | |
Ans. The mode represents the most frequently occurring value in a set of data. It can be used to determine the central tendency of a distribution and is particularly useful when dealing with categorical or qualitative data.
| 4. How is the mode different from the median and mean? | |
Ans. The mode, median, and mean are all measures of central tendency in statistics, but they represent different aspects of the data. The mode represents the most frequently occurring value, the median represents the middle value, and the mean represents the average value. While the mode and median are robust to extreme values or outliers, the mean can be heavily influenced by outliers.
| 5. Can a data set have more than one mode? | |
Ans. Yes, a data set can have more than one mode. If multiple values occur with the same highest frequency, then the data set is considered multimodal. On the other hand, if no value repeats or all values occur with the same frequency, the data set is considered to have no mode.
