What are summary statistics and why are they important?
Summary statistics are numerical values that summarize and describe the main features of a dataset. They provide insights into the data's central tendency, variability, and overall distribution.
Can you give me some examples of summary statistics?
Sure! Common examples include the mean, median, mode, range, variance, and standard deviation.
How do I calculate the mean and median?
To calculate the mean, add all the values together and divide by the number of values. The median is the middle value when the data is sorted.
Why is the median often preferred over the mean?
The median is less affected by outliers and skewed data, making it a better measure of central tendency in such cases.
