Answer:

There is a high positive correlation between sleep and exam performance

Explanation:

Correlation studies the degree of association between two variables. A correlation coefficient of 0.5 to 1 is regarded as a strong correlation, that is an increase in one variable will result in an increase in the other variable. A correlation coefficient that lies between 0.3 to 0.49 is regarded as moderately correlated while a value of 0 means that there is no correlation.

Thus, the result of this study shows that an increase in sleeping time will result in better exam performance.

There can be other factors that come into play, such as one's personality, the nature of the task and the group in general.
