While “average” and “mean” are often used interchangeably, they have distinct meanings in statistics. Understanding the difference can help you make better data-driven decisions!
🔹 Mean:
- The mean is a specific type of average, often referred to as the arithmetic mean.
- It’s calculated by summing up all the numbers in a dataset and dividing by the total number of values.
- Example: If you have the numbers 3, 5, and 8, the mean is (3+5+8)/3 = 5.33.
🔹 Average:
- The term average is more general and can refer to different types of averages, including mean, median, and mode.
- Depending on the context, the average can be mean (arithmetic average), median (the middle value when sorted), or mode (the most frequent value).
💡 Key Takeaway: All means are averages, but not all averages are means! The mean is just one way to measure the “central tendency” of data.
Understanding this distinction is essential for proper data interpretation, whether you’re analyzing sales performance or customer behavior.
