Question

Maria has the following scores on exams in her social studies class: 86, 75, 97, 58, 94, and 58.

Find the mean, median, and mode of the scores.

Should Maria’s social studies teacher use the mean, median, or mode of the exam scores to convince Maria that she needs to study more regularly for her exams? short answer

Answer 1

where does the number 94 appear twice at?

Answer 2

but the number 58 does, so does that mean there's a mode?

Answer 3

Mean:

To find the mean, you need to add up all the scores and divide by the total number of scores:

(86 + 75 + 97 + 58 + 94 + 58) / 6 = 78.0

So the mean score is 78.0.

Median:

To find the median, you need to put the scores in order from lowest to highest:

58, 58, 75, 86, 94, 97

The median is the middle score, so in this case it is 86.

Mode:

The mode is the score that appears most frequently. In this case, both 58 and 94 appear twice, so there are two modes: 58 and 94.

Based on the scores, it would be best for Maria's social studies teacher to use the mean score to convince her to study more regularly. The mean score of 78.0 indicates that Maria has room for improvement in her studying habits, as her scores are somewhat inconsistent. While the median of 86 is higher, it doesn't necessarily indicate that Maria needs to study more regularly, as it is possible to have a few low scores dragging down an otherwise good performance. Similarly, the mode doesn't give a clear indication of where Maria needs to improve.

Answer 4

I apologize for my mistake in the previous response. The number 94 appears only once in the given data set. So, there is no mode for this data set since no number occurs more than once.

Answer 5

Yes, you are correct. I apologize for the confusion. The number 58 appears twice in the data set, so the mode is 58. Therefore, the mode of this data set is 58.
