Question :- The mean score on any class test is the result of :-

1) Dividing the sum of all scores by the number of scores

2) Determining the middle score when all the scores have been listed from the highest to the lowest

3) Determining the most frequent score.

4) Adding all the scores and dividing by the most frequent score .

Solution :-

As we know that,

• The mean is the average of the numbers.
• To calculate average , we need to add up all the numbers, then divide by how many numbers there are.
• The median of a set of data is the middlemost number in the set. The median is also the number that is halfway into the set. To find the median, the data should first be arranged in order from least to greatest.
• If there is an odd number of terms, the median is the center term. = (n+1)/2
• If there is an even number of terms, add the two middle terms and divide by 2 = {(n/2 term)+(n/2+1) term}/2 .
• The mode is the value that appears most frequently in a data set.

So,

→ Mean = Average = (Sum of all data) / (how many data arr their.)

Or,

→ Mean = (sum of all scores) / (Total number of score) .

Therefore,

→ Mean = sum of all scores ÷ the number of scores.

Hence,

→ Mean = Dividing the sum of all scores by the number of

Scores. (Option 1) (Ans.)
