The following dot plot represents student scores on both the unit 1 and unit 2 math tests. scores are in whole number increments. part 1: looking at the data plots, which test do you think the students scored better on? do you think one of the tests has more variation than the other or is the variation about the same for both tests? use complete sentences in your answer and explain your reasoning. part 2: calculate the mean (rounded to the nearest whole number) and mean absolute deviation for the unit 1 test. part 3: do your results from part b prove or disprove your hypotheses from part a? use complete sentences in your answer and explain your reasoning.

A linear graph is one with a line which has the same slope throughout. In this case, you can tell that the line doesn't have the same slope all the way through because it flats and also decreases in one section.

Increasing will mean the line's slope is positive, or it tends to go upwards. The slope will be constant, 0, so it's just a horizontal line. The slope of the line will decrease is negative, and it tends to go downwards. In this case, this would mean that segment k is., as it seems to go upwards, l is constant, because it's a horizontal line, and would be decreasing because it's going downwards.

I might assume that the ant began moving away from the hole for 2 seconds, then stopped for 3 seconds, and then went back to the hole for 3 seconds again.
