Question

unit 1: lesson 3: practice problems - resource
1.) use the sentence starters and word bank below to help you interpret the value in the situation: note: you may need to use some words more than once
word bank
three - fourths maximum half speed middle intersection one - fourth minimum cars
a.) the smallest value is the ________ of the box plot. this shows the lowest speed of cars was recorded at ______ mph when crossing the ________.
b.) the largest value is the ________ of the box plot. this shows the highest ______ of cars was recorded at ______, when crossing the ________.
c.) the median shows that ________ of the cars had a ______ of ______ mph when crossing the ________.
d.) the first quartile (q1) shows that ________ of the ______ had a ______ of ______ mph when crossing the ________.
e.) the third quartile (q3) shows that ________ of the cars had a ______ of ______ mph when crossing the ________.
2.) typical number means look for the average and median of the given numbers.
3.) look for the average. try writing a list from the dot plot. for example, i see one 5, so i am starting my list with 5, then two 5.5, 5.5, and so on!
4.) skip #4

Explanation:

Step1: Identify minimum in box - plot

The smallest value in a box - plot is the minimum.

Step2: Identify maximum in box - plot

The largest value in a box - plot is the maximum.

Step3: Recall median property

The median represents the middle value, so half of the data lies below it.

Step4: Recall first quartile property

The first quartile (Q1) represents the value below which one - fourth of the data lies.

Step5: Recall third quartile property

The third quartile (Q3) represents the value below which three - fourths of the data lies.

Answer:

a. minimum; [speed value]; intersection
b. maximum; speed; [speed value]; intersection
c. half; speed; [speed value]; intersection
d. one - fourth; cars; speed; [speed value]; intersection
e. three - fourths; speed; [speed value]; intersection
