Analyze the residual

I am going to do the residual analyze. So I need the residual plot. I am not sure how to fix the error.

DATA Golf;
INPUT Season $ Score;
Datalines;

Summer 87
Summer 90

proc print;
run;

PROC REG DATA=Golf;
Model Score =Season;

Run;

ERROR: Variable Season in list does not match type prescribed for this list.

The message is clear.

A regression is performed between 2 numeric variables; you have a character variable here.

How to correct it?

what are you trying to achieve?

Residual vs fit plot, normal qq plot. Response is Score.

Note that there can only be one predicted value for each season (the season mean score). Try this:

PROC glm DATA=Golf plots=DIAGNOSTICS(LABEL UNPACK);
class season;
Model Score = Season;
Run;
