- What is the purpose of the standard deviation? The standard deviation measures the amount of variation or dispersion from the mean value. It is used to calculate the margin of error and to compare the variability of different data sets.
- What is the difference between mean and median? The mean is the average value of the data set, while the median is the middle value when the data is sorted in ascending order. The median is more resistant to outliers and skewed distributions.
- How is the mode calculated? The mode is the value that appears most frequently in the data set. If there are multiple modes, the data set is said to be bimodal or multimodal.
