What is this table of data recording?
- car value decreasing over time
- car value increasing over time
Yes. The value of the car is decreasing as time passes
Try again. The years have increased, but not the value of the car
Which is the BEST title of a line graph made for this table about a car?
- Value
- Years
- Line Graph
- Car Value
Try again. You need to make sure you identify what is being valued.
Try again. This is the unit of time, but not the data that is being represented.
Try again. This is the type of graph, but not the title of the graph that the data table contains.
Yes. The table’s labels and heading help to guide you to this conclusion.
The line graph shows the change in value of a different car over time. What is the value of this car in 2019?
- a little under $15,000
- a little over $15,000
- a little under $20,000
- a little over $20,000
Correct. The graph shows the value of the car being worth a little under 15,000
Try again. The graph shows the value of the car slightly below the $15,000 line
Try again. The graph shows the value as being a small amount under $15,000
Try again. The graph shows the value around $20,000 in 2019.
In which year is the car’s value the MOST?
- 2016
- 2020
- 2015
- 2018
Try again. In 2016, the value was $22,500
Try again. In 2020, the value was $10,000.
That is correct! In 2015, the car was at its highest value of $24,000
Try again. In 2018, the value was $17,500.
What does this data table record?
- the number of people in a store
- times of the day
- number of times one person visited a store
- number of people who arrive in the morning
Correct. This records the number of people in the store at times throughout the day
Try again. While the time of the day is important, it is not the value that is being collected.
Try again. This table looks at more than 1 person throughout the day
Try again. This records the people who are at the store at times other than just the morning.
This graph charts number of people in a store over one day. At which time are the MOST people in the store?
- 1:00 PM
- 10:00 AM
- 2:00 PM
- 12:00 PM
Great job! There were 22 people in the store at 1:00 PM
Try again. There were only 2 people in the store at 10:00 AM
Try again. There were only 15 people in the store at 2:00 PM; more were present at another time
Try again. There were 10 people in the store at that time, and more were present later.
At which times were the same number of people in the store?
- 11:00 AM and 3:00 PM
- 4:00 PM and 5:00 PM
- 10:00 AM and 1:00 PM
- 3:00 PM and 4:00 PM
Yes. There were 5 people in the store at both these times.
Yes. There were 4 people in the store at both these times
Try again. These are the times with the most and least number of people
Try again. These times are in a row, but they do not have the same value.
At which times were more than 10 people in the store?
- 1:00 PM and 2:00 PM
- 4:00 pm and 5:00 pm
- 10:00 AM and 11:00 AM
- 2:00 PM and 3:00 PM
Correct. 1:00 PM had 22 people, and 2:00 PM had 15 people present
Try again. These times did not have more than 10 people. 4:00 PM had 4 people, and 5:00 PM had 4 people present
Try again. These times did not have more than 10 people. 10:00 AM had 2 people present, and 11:00 AM had 5 people present
Try again. 2:00 PM does have more than 10 people, but 3:00 PM does not.
What change occurs in the number of people from 1:00 PM to 3:00 PM?
- The number of people decreases then increases.
- The number of people decreases, then decreases again.
- The number of people increases, then increases again.
- The number of people increases then decreases.
Try again. The number of people decreased from 2:00 PM to 3:00 PM.
Yes! The number of people decreases from 1:00 PM to 2:00 PM and then again from 2:00 PM to 3:00 PM
