    Three steps to complete the assignment

    Step 1: Review the Rubric

    • Before you submit your work, review the rubric at the bottom of this assignment.
    • Use the rubric as a checklist to determine whether you are ready to submit your work.

    Step 2: First Draft

    • Commit a good-faith effort to address each item in the Prompt section below.
    • Please be sure to number your responses and include “white space” between problem numbers. This improves the readability and flow of your work. I cannot give feedback and grade jumbled work.
    • Use either of the following options to submit your work.
      OPTION 1: You can submit a text-entry assignment (i.e. typing your answers in Canvas). To learn how to submit a text-entry assignment, use these (opens in a new tab).
      OPTION 2: You can upload your paper-and-pencil work (or the digital equivalent). To learn how to upload your paper-and-pencil work, use these (opens in a new tab).

However, to earn full credit, you are not required to submit a final draft for this assignment. But if you do submit a final draft, I will only grade it if you submitted a good-faith effort on your first draft.
    • Warning – I will only grade your most recent submission. So if you choose to submit a final draft, please do not leave anything out, and please do not direct me to read an earlier submission. To maximize your score, your most recent submission (at the time I begin grading) must be complete.

    Context

    Students researching backpack weights gathered data from 45 elementary school children in the 3rd and 5th grades. The variable is percent of body weight carried in the school backpack. So a child who weighs 60 pounds and carries 9 pounds has a variable value of 15% (9 60 = 0.15 = 15%). The American Chiropractic Association (ACA) recommends that children carry no more than 10% of their body weight.

    Week 6 Discussion Attachment

    The regression equation is:
    Height = 6.5235(Age) + 75.9137

    Input and output variables:
    The input variable (x) is Age in years.
    The output variable (y) is Height in centimeters.
    The value 75.9137 represents the predicted height at age 0 (the y-intercept).

    Correlation coefficient:
    r = 0.9898
    This indicates a very strong positive linear relationship between age and height. As age increases, height increases nearly perfectly linearly.

    Coefficient of determination:
    R = 0.9797
    This means about 97.97% of the variation in height can be explained by age using this linear model. This shows the model fits the data extremely well.

    Appropriate interval of ages:
    This regression equation is appropriate for ages 1 to 11 years, since that is the range of the data used to build the model. Predictions outside this range may not be reliable.

You may ask artificial intelligence what a command does, but your answer must be in your own words.

    Context

    We will use our unique IAT data sets to learn how to create a histogram using StatCrunch. We will also practice what we’ve learned about describing a histogram. We are interested in describing the distribution of IAT participants’ ages when they took the IAT test.

    Data

    All directions in this assignment open in a new tab.

    • Login and open StatCrunch ().
    • Open your IAT sample data set in StatCrunch ().
    • Create a histogram of the ages of the IAT participants ().
    • Download the StatCrunch output window, your histogram ().

    Prompt

    In your initial post, respond to the following prompt. But first, be sure to complete the work in the Data section above.

    Question 1

    Describe the distribution of IAT participants’ ages in your sample. Your description should include: shape, center, spread, a typical interval of representative ages, and any apparent outliers (unusual ages). Be sure to embed your histogram in the textbox along with your response – and include the Alt Text (). Please do not submit your histogram as an attachment.

    Question 2

    Create a second histogram for the distribution of ages, and adjust the bin width (). Try both smaller and larger bin widths. Choose a bin width so that your second histogram does not look like the first. Also, embed your second histogram in the textbox with your response. Indicate which histogram is better for analyzing the data (your first embedded histogram or your second). Explain why.

    Question 3

    Your random sample was obtained from the population of participants for your chosen IAT data set. Based on the histogram from your random sample, how would you describe the population of participants for your chosen IAT data set? Do you think the IAT population is similar to the U.S. population?
