Re: not understanding the graph

the line doesn't match the dots. I get the last few games he has been poor due to the playoffs and type of competition as well as game 1 he was rusty.

The dashed line is called a trend line. It takes all the data points and uses a statistical method called the least squares method to find the best fit for a straight line though data points.

The idea here is to look at all his performance over the past 20 games and see if there is an overall upward or downward trend.

As you can see his performances were much better overall early last year compared to the last half of last year. And now he has started off poorly.

So the downward slope of the trend line just shows how badly he has played overall since the beginning of last year.

I apologize for being an engineer.
