What do you know so far?
You are about to watch a video about Tempest Jones, an 8th grade student who dreams of a career as a meteorologist (a weather forecaster). Tempest is an intern at a local weather station and she uses her math and science skills to prepare data for a meteorologist on TV!
But first, take this short quiz to see what you know about scatter plots. It’s OK if you aren’t sure of the answers.
After the video, you will do three practice problems, then take another short quiz so you can see what you learned.
1
Tempest needs to turn this table into a visual graphic that can be shown on TV while the meteorologist speaks. Which of the following graphs shows the information contained in the table?
a
b
c
d
2
Tempest is preparing graphs for a special about staying hydrated during hot, humid weather. She collected data on how the soccer team’s water consumption changed as the temperature changed.
The data in this graph appears to have a:
The data in this graph appears to have a:
a
Negative association
b
Positive association
c
Circular association
d
No association

Tempest has an idea for a new TV episode: how temperature affects the decisions people make. She’s creating a graph from data about people refilling their water bottles when hiking.
If additional data were added to the chart, which data point would seem to be an outlier?
If additional data were added to the chart, which data point would seem to be an outlier?
a
(36, 700)
b
(22, 400)
c
(25, 100)
d
(26, 425)

It’s Tempest’s job to draw lines of best fit on the graphs before they air on TV. She is working on a story about how temperature affects beach attendance in the summer. Which of the following would best serve as a line of best fit?
a
b
c
d

Tempest is curious about the data points missing from this graph.
What would be a reasonable estimate for the number of permits sold on a day when it’s 25 degrees Celsius?
What would be a reasonable estimate for the number of permits sold on a day when it’s 25 degrees Celsius?
a
25
b
100
c
175
d
250

How confident are you about solving problems involving scatter plots and graphing data?
a
Very confident
b
Confident
c
Somewhat confident
d
Not confident
