CHSAA Seeding Index – Hockey data

The 2021 hockey state tournaments will be determined in part and seeded by the CHSAA Seeding Index.

This seeding index uses three sources of data:

• CHSAA RPI
• CHSAANow coaches poll
• MaxPreps Rankings

These data points have been combined, with each counting for 1/3 of the formula, and the result of that data is below.

Each ranking system is translated into a percentage in order to combine them. To do this:

• Teams have their total points in the coaches poll divided by the total possible points. For example, if a poll has 20 voters, there are 200 possible points as a first-place vote is worth 10 points.
• The RPI and MaxPreps rankings determine their percentage by comparing every team to the maximum value in that classification. For example, if the maximum RPI value in a class is .700, every other team in that classification is compared to that value.
• To account for some negative values in the MaxPreps ratings, the minimum value is added to every value in the classification to ensure the lowest possible rating is 0, and not negative. This only occurs if the minimum value in a classification is negative.
• These percentages are then added together and divided by three, so that each accounts for 1/3 of the final formula.
