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.
