To calculate the mean mark of the scores obtained by 7 pupils in a Mathematics test, follow these steps:
1. List the scores: 62, 57, 28, 43, 15, 62, and 90.
2. Sum the scores: Add all the scores together to get the total sum.
- [tex]\( 62 + 57 + 28 + 43 + 15 + 62 + 90 = 357 \)[/tex]
The total sum of the scores is 357.
3. Count the number of pupils: Determine the total number of scores provided.
- There are 7 scores, so there are 7 pupils.
4. Calculate the mean: The mean is calculated by dividing the total sum of the scores by the number of pupils.
- Mean [tex]\( = \frac{357}{7} = 51.0 \)[/tex]
So, the mean mark of the scores obtained by the 7 pupils is 51.0.
