Rolinda's first five Spanish test scores are 85, 85, 60, 62, and 59.
a. Find the mean, median and mode of the scores. Round to the nearest tenth, if necessary.*
b. Which of these measures best supports Rolinda's claim that she is doing well in her Spanish class?
c. Why is Rolinda's claim misleading?
*I already figured that out. Thanks!
Ms. Sue, Writeacher, Reed, Damon please help me guys!
Actually, A is not posted correctly here. 70.2 is the mean but the other two were not posted.
Sum: 351 85 + 85 + 60 + 62 + 59
Min 59
Max 85
Range 26 85 - 59
Median 62
Mode 85
Mean 70.2
Median=62 Mode=85 Mean= 70.2
Next, we move on to Part B. The measure that supports Rolinda’s claim that she is doing well in her Spanish class is the mode, because it is the highest measure out of the three.
The answer to Part C is as follows: This is misleading because the mode is not an accurate representation of all of Rolinda’s test scores and the range that they cover, it only represents Rolinda’s highest score, which she happened to score twice
The answer to A is 70.2. To find the mean, you add the number and then divide that by the number of number that are listed.
85 + 85 + 60 + 62 + 59 = 351
351/ 5 = 70.2
I think b is 85
And I think to c, the answer is: Her claim is misleading because the score of 85 is her first test score, and the scores slowly decrease after that.

1. a. Mean: 70.2 Median: 62 Mode: 85
b. Mode, because its the highest out of the three.
c. This is misleading because the mode is not an accurate representation of all of Rolinda’s test scores and the range that they cover, it only represents Rolinda’s highest score, which she happened to score twice.
Wow helper, 4 hours ago?
What is the Answer To A?
thx I better get this right
A. For the mean you add all the numbers and divide it by 5. gets you 70.2
now for the median it is the average number so 62
Mode is the number you seen more often 85
B. Mode since it is the larger number
C. The claim is misleading because mode represents there highest score and Rolinda scored it twice
