FAQs on Examples: Mean & Range of Data- 1 Video Lecture - Advance Learner Course: Mathematics (Maths) Class 6
| 1. What is the meaning of data in statistics? |  |
Ans. In statistics, data refers to a collection of facts, observations, or measurements that are gathered through various methods. It can be numerical, categorical, or even textual information that is used for analysis and interpretation.
| 2. How is the mean calculated for a set of data? | |
Ans. The mean of a set of data is calculated by summing up all the values in the dataset and dividing it by the total number of values. This provides the average value or central tendency of the data.
| 3. What is the range of data? | |
Ans. The range of data refers to the difference between the maximum and minimum values in a dataset. It provides a measure of the spread or variability of the data points.
| 4. How can the mean be affected by outliers in a dataset? | |
Ans. Outliers, which are extreme values that lie far from the other data points, can significantly impact the mean of a dataset. If there are outliers, the mean tends to be pulled towards these extreme values, causing it to be biased and not representative of the overall data.
| 5. Is the mean always the best measure of central tendency for all datasets? | |
Ans. No, the mean may not always be the best measure of central tendency for all datasets. It is sensitive to outliers and can be influenced by extreme values. In cases where the dataset is skewed or contains outliers, other measures like the median or mode may provide a more accurate representation of the data's central tendency.
