## FAQs on Examples: Mean, Median and Mode Video Lecture | Crash Course: Class 9

 1. What is the mean in statistics?
Ans. The mean in statistics is a measure of central tendency that represents the average value of a set of numbers. It is calculated by summing up all the values in the set and then dividing the sum by the total number of values.
 2. How is the median calculated?
Ans. The median is calculated by arranging a set of numbers in ascending or descending order and finding the middle value. If the set has an odd number of values, the middle value is the median. If the set has an even number of values, the median is the average of the two middle values.
 3. What is the mode in statistics?
Ans. The mode in statistics refers to the value that appears most frequently in a set of numbers. It is possible for a set to have multiple modes if there are two or more values that occur with equal frequency.
 4. How can mean, median, and mode be used to describe a dataset?
Ans. Mean, median, and mode provide different insights into a dataset. The mean gives an overall average value, the median represents the middle value that divides the dataset into two halves, and the mode identifies the most frequently occurring value. By using these measures, we can understand the central tendency, variability, and distribution of data.
 5. Is it possible for the mean, median, and mode to have different values in a dataset?
Ans. Yes, it is possible for the mean, median, and mode to have different values in a dataset. This occurs when the dataset has a skewed distribution or contains outliers. In such cases, the mean may be influenced by extreme values, causing it to differ from the median, which is less affected by outliers. Additionally, if the dataset has multiple values occurring with equal frequency, the mode may be different from both the mean and median.
