Frequently Asked Questions
Q.What is the difference between Mean and Median?
The Mean is the arithmetic average. The Median is the middle value when the numbers are sorted. The Median is less affected by extreme outliers than the Mean.
Q.What is Standard Deviation?
Standard deviation measures the amount of variation or dispersion in a set of values. A low standard deviation indicates that the values tend to be close to the mean.
Q.What is the Mode?
The Mode is the number that appears most frequently in a dataset. A dataset can have one mode, more than one mode, or no mode at all.
