keskivertoarvo

Keskivertoarvo, meaning "average value" in Finnish, is a statistical term referring to the arithmetic mean. It is calculated by summing all the values in a dataset and then dividing by the number of values. This provides a central tendency of the data, giving a representative value for the entire set.

For example, if you have the ages of five people as 20, 25, 30, 35, and 40, the keskivertoarvo would be (20 + 25 + 30 + 35 + 40) / 5 = 150 / 5 = 30. The average age is 30.

The keskivertoarvo is a fundamental concept in statistics and is widely used in various fields, including economics, science, and everyday life, to summarize and understand data. It is sensitive to outliers, meaning extreme values can significantly affect the mean. In situations with significant outliers, other measures of central tendency like the median might be more appropriate. The calculation is straightforward and its interpretation is generally intuitive, making it a widely accessible statistical tool.
