What is the difference between mean, median, and mode?

The mean is the arithmetic average (sum divided by count). The median is the middle value when numbers are sorted. The mode is the most frequently occurring value. Each measures central tendency differently — the mean considers all values, the median is robust against outliers, and the mode shows the most common value.

When should I use median instead of mean?

Use the median when your data has outliers or is skewed. For example, household income data is typically reported as a median because a few extremely high incomes would pull the mean upward, making it unrepresentative of the typical household. The median gives a better picture of the 'middle' value.

What if there is no mode in my data?

If every value in your dataset appears exactly once, there is no mode. The calculator will indicate this. Some datasets have multiple modes (bimodal, trimodal) when two or more values share the highest frequency. The calculator identifies all modes when they exist.

How do I calculate a weighted average?

This calculator computes the simple (unweighted) average. For a weighted average, each value is multiplied by its weight, the products are summed, and the total is divided by the sum of weights. If you need weighted averages, you would need to perform the calculation manually using the weighted formula.

Can I use this calculator for grades?

Yes, you can enter your grades to calculate your average. For a simple average, enter just the grade values. For a weighted GPA, you would need to account for credit hours or course weights, which this simple calculator does not handle directly.

What is the range in statistics?

The range is the difference between the maximum and minimum values in your dataset. It measures the spread of the data. For example, if your values are 10, 15, 20, 25, and 30, the range is 30 - 10 = 20. The range is a simple measure of variability but is sensitive to outliers.
