Use sleep and activity in school, determine if the correlation is positive or negative. does sleeping improve your performance? if it does that is a positive correlation. hours of sleep increase, activity increases. use that example to find a negative correlation. when sleep is deprived, activity goes down. do you get it?

Positive correlation:  As total hours spent on studies increases the test scores increases.
So you can make up a table like this:

Hours Studied   Test Score %
      20                  40
      25                  50
      30                  60
      35                  70
      40                  80
      45                  90

Negative Correlation:  As the temperature increases, the number of winter coats sold by some local store decreases:

Temperature      Number of winter coats sold
      10                        200
       20                       150
       30                       100
       40                         50
