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.

Many parts that are meant to which are confusing and that is a good question for To answer all of these parts, you must know how to make a graph an a plot( Dot plot ).

Take a moment to carefully read the question. Take prior knowledge an other knowledge that you already know and repeat this question in your own words.

If you did put it in your own meaning of what you think it is asking you don’t need any help from me. If you do, comment and I can tell you. If you still don’t understand the question, read it over a few times.

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
