How to read the set index

What is the typical single?
The median fair value of the set's Near Mint English singles — the price in the middle, so one chase card can't drag it up. Fair value comes from real sales only; the marketplace's Market Price is shown on card pages but never counted.
What does the index line show?
Each week the set's cards are compared with the week before and the typical change is added to a line that starts near 100. Above 100 the set's cards sell for more than they did a year ago; the 90-day figure is that same line, read over the last quarter.
How is popularity scored?
Out of 100, against the rest of the game: how much the set's cards sell for, how many of them sell each week, how many cards it holds and how its index has moved. It ranks sets; it isn't a price.
