Question

PLZ HELP I WILL STAR MARK BRAINLIEST A survey of a group of seventh graders and a group of teachers at a local middle school asked how many siblings they each have. The dot plots below show the results. 
Which compares the medians of the data?
The median for the students is 4 and the median for the teachers is 8.The median for the students is 2 and the median for the teachers is 3.The median for the students is 4 and the median for the teachers is 3.The median for the students is 2 and the median for the teachers is 8.

Answer 1

Answer:

The median for the students is 2 and the median for the teachers is 3.

Step-by-step explanation:

We can find the median by writing the numbers represented in each dot plot in order.

For the students,

0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4

The middle value is between 2 and 2; this makes it 2.

For the teachers,

0, 1, 1, 1, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 6, 8

The middle value is between 3 and 3; this makes it 3.

This means the second choice is correct.

Answer 2

Answer: The median for the students is 2 and the mean for the teacher is 3.

Step-by-step explanation:

If it is too hard to calculate the median from the graph, you can list the data in numbers and find the middle number.

For graph 1, the numbers are:

0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4,  and 4.

The middle value is 2, which is detectable thanks to the mode.

For graph 2, the numbers are:

0, 1, 1, 1, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 6 and 8.

The middle value is 3, which is also a mode.

So your answer is B.
