b) Are there any overall patterns in the data set? Striking deviations? Use mathematical reasoning to justify your answer. (2 points)








c) Calculate the measures of spread for Mrs. Hampton’s class data. Justify your response by describing the process used to find each measure. (2 points)










































d) Which is a better measure of spread: range or interquartile range? Why? (2 points)











e) What does the value of the mean absolute deviation tell you about the spread of the data? (2 points)

Answer:

What the absolute deviation tells me about the spread of data is, that there is a deeper mean to the mean. First you have to find the actual mean. Next, you find the mean for the lower and upper quartiles. After that, you have to find the absolute deviation for the lower and upper quartiles.  

Step-by-step explanation:

I really hope this helps!

(Also this answer is for Part E)

Answer: A) The histogram is skewed left meaning that the median will be more than the mean of the data. As the study goes onward in terms of age, more and more children are studied to play at least an hour a week of video games. Barley any children below the age of 5 play video games for at least an hour a week, but once they hit the age of 6, more and more kids are playing video games. Kids aged fifteen to seventeen have the most amount of kids that do play at least an hour of video games per week. In a graph, this may show a J-shaped curve that starts low, then has a large increase to eventually level off and begin gradually getting larger as the ages increase.B) The following statement, “Children are typically introduced to video games between the ages of six to eight” is a true statement. The graph shows that a very small percentage of children from birth to five years old play video games, but suddenly, once they have turned 6, there is practically a 60% increase in how many kids are playing video games one hour a week. It is from the age 6 that the kids start off and are introduced to the video games, as more and more kids end up playing as well as the grow older.c) Knowing that five hundred families that lived in varied cities were randomly surveyed for this data, then it is possible to make a valid conclusion. To make accurate and valid conclusions, the data should be a good representation of the overall population, one that is large and random. The data collected was not all from one specific area, and instead was from a large sample size from different cities are regions all over. This was also done randomly, and did not only focus on people more or less likely to play video games. This means that it is possible to make valid conclusions.

A researcher is comparing the effectiveness of three devices designed to help people who snore. There are 120 people who snore participating in the experiment. Using a table of random digits, the researcher will randomly place the participants into three equally sized treatment groups suitable for comparison.

Which design is the most appropriate for this experiment?

A Randomly number each person with 1, 2, or 3. Assign the people labeled 1 to the device 1 group, the people labeled 2 to the device 2 group, and the people labeled 3 to the device 3 group.
B Number each participant from 1 to 120. Reading numbers from left to right from a random number table, identify 80 unique numbers from 1 to 120. Assign the people whose labels are the first 40 numbers to the device 1 group. Assign the people whose labels are the second 40 numbers to the device 2 group. Assign the remaining people to the device 3 group.
C Number each participant from 000 to 119. Reading numbers from left to right on a random number table and looking at three digits at a time, identify 80 unique three-digit numbers from 000 to 119. Assign the people whose labels are the first 40 numbers to the device 1 group. Assign the people whose labels are the second 40 numbers to the device 2 group. Assign the remaining people to the device 3 group.
D Select a participant, and identify the first digit reading numbers from left to right on a random number table. If the first digit is a 1, 2, or 3, assign the participant to the device 1 group. If the first digit is a 4, 5, or 6, assign the participant to the device 2 group. If the first digit is a 7, 8, or 9, assign the participant to the device 3 group. If the first digit is a 0, skip that digit and move to the next one to assign the participant to a group. Repeat this process for each participant.
