max is analyzing the test scores he earned in his biology class. the class had 7 tests, on which he scored 85, 93, 78, 90, 88, 97, and 88. what is the mean of the data set? what is the median of the data set? what is the mode of the data set?

Answer

Explanation:

Step1: Calculate the sum of scores

$85 + 93+78 + 90+88+97+88=629$

Step2: Calculate the mean

The mean $\bar{x}=\frac{629}{7}\approx89.86$

Step3: Arrange scores in ascending - order

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

Step4: Find the median

Since there are 7 (an odd number) data - points, the median is the 4th value, which is 88.

Step5: Find the mode

The mode is the number that appears most frequently. Here, 88 appears twice and other numbers appear once, so the mode is 88.

Answer:

Mean: $\approx89.86$ Median: 88 Mode: 88
