Impute with computed value

This processor imputes missing values with mean, median or mode.

The mean is the sum of values of a data set divided by number of values. This is what is most often meant by an average.

The median is the middle value separating the greater and lesser halves of a set of values

The mode is the most frequent value in a set of values

For example, given the values 1, 2, 2, 3, 4, 7, 9:

• Mean is 4 ((1+2+2+3+4+7+9) / 7)

• Median is 3 (1, 2, 2 – 3 – 4, 7, 9)

• Mode is 2 (1, 2, 2, 3, 4, 7, 9)
