Common questions about Mean, Median, Mode of 15, 25, 35, 45, 55, 65, 75
What are the mean, median, and mode of 15, 25, 35, 45, 55, 65, 75?
Mean (average) = (15 + 25 + 35 + 45 + 55 + 65 + 75) / 7 = 45.0000. Median (middle value of sorted data) = 45. Mode (most frequent value) = 15 and 25 and 35 and 45 and 55 and 65 and 75. Range = 75 − 15 = 60.
When should you use mean vs median?
Use the mean when your data is symmetric and has no extreme outliers. Use the median when data is skewed or has outliers — for example, income data (a few very high earners skew the mean upward). For {15, 25, 35, 45, 55, 65, 75}, the mean is 45.00 and the median is 45. They are close, indicating the data is roughly symmetric.
