Mean scores are used to determine the average performances of students or athletes, and in various other applications. Mean scores can be converted to percentages that indicate the average percentage of the score relative to the total score. Mean scores can also be converted to percentages to show the performance of a score relative to a specific score. For instance, a mean score can be compared to the highest score with a percentage for a better comparison. Percentages can be a useful means of statistical analysis.
Find the mean score if not already determined. The mean score can be determined by adding up all the scores and dividing it by "n," the number of scores.
Determine the score that you want to compare the mean score to. You may compare the mean score with the highest possible score, the highest score, or a specific score.
Divide the mean score by the score you decided to use in step 2.
Multiply the decimal you obtain in step 3 by 100, and add a % sign to obtain the percentage. YOu may choose to round the percentage to the nearest whole number.
Individual scores can be compared to the mean score by similar means to provide further methods of analysis.
