Hi there!

To calculate the mean, we first need to sum all the scores and divide by the total number of tests.

85+93+78+90+88+97+88=619

619/7≈88.43

Mean≈88.43

Next, we will determine the median by arranging the scores in ascending order.

78,85,88,88,90,93,97

To find the median, we look for the middle score, which is 88.

Median: 88

Lastly, we identify the mode, which is the score that occurs most frequently. Here, 88 appears twice while the others appear once, making 88 the mode.

Mode:88

I hope this is useful!

Max received the scores of 85, 93, 78, 90, 88, 97, and 88 from 7 tests.

We are tasked with finding the mean, median, and mode of this data.

$mean =sum of the all observations /total number of observations$

$mean=(78+80+85+88+88+90+97)/(7)=606/7=86.57we know that to find median we have check first whether we have odd or even number of terms.we have 7 data set which means odd.so the median=[tex] (n+1)/2$

$(7+1)/2=4$

The median is represented by the 4th term in this ordered dataset.

Since we arranged the scores in ascending order, we find that 88 is the 4th score.

The mode indicates the highest frequency of occurrences.

Given that 88 is repeated twice, it is the mode for this dataset.
