  • Question 5 (request help)

    A distribution that is not symmetric is called skewed. A distribution that is skewed left shows data that is more spread out on the left side than on the right side. A
    distribution that is skewed right shows data that is more spread out on the right side than on the left side.The box plot shows the heights in feet of several trees.

    a. Explain how you know the distribution is not symmetric.

  • Question 5 (request help)

    b. Is the distribution skewed left or skewed right? Explain.

  • Skewed to the

    c. Use appropriate measures to describe the center and spread of the distribution. Justify your choice of measure based on the shape of the distribution.

  • Center:   feet
    Spreed:   feet

  • Question 6 (request help)

    Model with Mathematics Draw a line plot for which the median is the most appropriate measure to describe the center of the distribution.

  • Question 7 (request help)

    Persevere with Problems Explain why you cannot describe the specific location of the center and spread of the box plot shown using the most appropriate measures.

  • Question 8 (request help)

    Justify Conclusions Tyra created the dot plot shown to represent the ages of the staff of the community pool. She concludes that since there is a peak at 19, the median is 19. She also concludes the two data values that are 25 to be outliers, so there are no gaps. Evaluate her conclusions.

  • The median is 19:   
    25 is an outlier:
