Isolated power

The ISO statistic takes into account the extra base hits. It shows how many power does the player use to perform them. For example, the performer with a single and a double has bigger batting average than the performer with only one double. Their ISO will be the same.

The double brings one point for the player, triple equals 2 points and home run adds 3 points for the player. Their sum is divided by the difference between the number of at-bats or slugging percentages and the batting average.
