Asurvey was taken of students in math classes to find out how many hours per day students spend on social media. the survey results for the first-, second-, and third-period classes are as follows: first period: 2, 4, 3, 1, 0, 2, 1, 3, 1, 4, 9, 2, 4, 3, 0 second period: 3, 2, 3, 1, 3, 4, 2, 4, 3, 1, 0, 2, 3, 1, 2 third period: 4, 5, 3, 4, 2, 3, 4, 1, 8, 2, 3, 1, 0, 2, 1, 3 which is the best measure of center for third period and why?

Median, because there is 1 outlier that affects the center

Step-by-step explanation:

Ordering the data from the least value to the highest value we get:

0, 1, 1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 8

Because there are 16 values, positions 8 and 9 are in the half. Both correspond to value 3. Then, the median is 3.

Other measures of center, like the mean, are not the best options because of the presence of the 8 value, which is atypical.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
