FAQs on Median & Mode- 5 Video Lecture - Statistics for Economics - Class XI - Commerce
| 1. What is the median in statistics? |  |
Ans. The median is a measure of central tendency in statistics. It represents the middle value of a dataset when the values are arranged in ascending or descending order. To find the median, one needs to determine the middle value or the average of the two middle values if there is an even number of values.
| 2. How is the median different from the mean? | |
Ans. The median and the mean are both measures of central tendency, but they differ in how they are calculated and what they represent. The median represents the middle value of a dataset, while the mean represents the average value. The median is less affected by extreme values or outliers, whereas the mean is influenced by all values in the dataset.
| 3. What is the mode in statistics? | |
Ans. The mode is a measure of central tendency in statistics that represents the most frequently occurring value in a dataset. Unlike the median and the mean, the mode does not require any calculations or ordering of values. It is simply the value that appears the most number of times in the dataset.
| 4. Can a dataset have more than one mode? | |
Ans. Yes, a dataset can have more than one mode. If there are multiple values that occur with the same highest frequency, then the dataset is considered to be multimodal. For example, in a dataset of test scores where both 70 and 80 appear the most number of times, both values would be considered as modes.
| 5. How can the median and mode be used to describe a dataset? | |
Ans. The median and mode provide additional information about the distribution of values in a dataset. The median indicates the middle value and helps identify the "typical" value in the dataset. It is especially useful when there are outliers that could heavily influence the mean. The mode, on the other hand, identifies the most frequently occurring value or values, which can give insights into the common characteristics or patterns within the dataset.
