FAQs on Median & Mode- 3 Video Lecture - Statistics for Economics - Class XI - Commerce

1. What is the median and mode in statistics?
Ans. The median is a measure of central tendency in statistics that represents the middle value of a dataset when it is arranged in ascending or descending order. It divides the dataset into two equal halves. On the other hand, the mode is the value that appears most frequently in a dataset.
2. How is the median calculated?
Ans. To calculate the median, you need to arrange the dataset in ascending or descending order and then determine the middle value. If the dataset has an odd number of values, the median is the middle value itself. If the dataset has an even number of values, the median is the average of the two middle values.
3. What is the significance of the median in statistics?
Ans. The median is an important measure of central tendency in statistics because it is less affected by extreme values or outliers compared to the mean. It provides a better representation of the typical or central value of a dataset, especially when there are extreme values present.
4. How is the mode determined in a dataset?
Ans. To determine the mode in a dataset, you need to identify the value that appears most frequently. If there is no value that appears more often than others, the dataset is said to have no mode or to be multimodal if there are multiple values with the same highest frequency.
5. Can a dataset have multiple modes?
Ans. Yes, a dataset can have multiple modes. When multiple values appear with the same highest frequency in a dataset, it is considered to be multimodal. This means that there are multiple values that occur most frequently, making them all modes of the dataset.
