Descriptive Statistics
Descriptive statistics summarize and describe the main features of a dataset. Common measures include mean (average), median (middle value), mode (most frequent value), and measures of spread like standard deviation and range.
Measures of Central Tendency
These measures describe the center of a data distribution. The mean is the arithmetic average, the median is the middle value when data is ordered, and the mode is the most frequent value.
Measures of Dispersion
These measures describe how spread out the data is. Range shows the difference between maximum and minimum values, variance measures the average squared deviation from the mean, and standard deviation is the square root of variance.

Frequently Asked Questions
What is the difference between mean, median, and mode?
The mean is the average of all values, the median is the middle value when data is ordered, and the mode is the most frequently occurring value. Each measure provides different insights about the data distribution.
How do I interpret standard deviation?
Standard deviation measures how spread out the data is from the mean. A smaller standard deviation indicates that the data points are closer to the mean, while a larger standard deviation indicates more spread in the data.
What is variance used for?
Variance measures the average squared deviation from the mean. It's useful for understanding the spread of data and is the square of the standard deviation.
