15. I Can… Interpret data from a table Interpret data from a circle graph
Interpret data from a line graph
Interpret data from a bar graph
TOC #7 Interpret data

16. Review from yesterday!
Data Interpretation in 4 Steps
Detailed Version
Step 1: Carefully examine the table, graph, or diagram.
Step 2: Look for patterns/trends in the way the data is organized and displayed.
Step 3: Read the question. Determine specifically what it is asking. Also read the answer choices.
Step 4: Again examine the visual to find the answer.
Note: often the answer will not be obvious, but it can be determined by analyzing patterns/trends of the displayed data.

Data Tables
Tables are used to organize and display independent variable and dependent variable information/data.

18. Different types of charts, tables, and graphs
Pie Charts (circle graphs)
…are circular charts divided into sectors (slices).
Best used for comparing parts to a whole.
The total amount should equal 100%.
Works well for comparing 6 or fewer items, but more than six items becomes difficult to view and interpret.

19. Pie Chart/Circle Graph: Example
Starts with data
in a table like this
Transfer the data into a circle graph like this
Reminder: the sum of the sectors must equal 100%
…is comparing parts to a whole, so a pie cart is best for this data.
Parts: nitrogen, oxygen, other. Whole: Earth’s Atmosphere

20. Pie Chart/Circle Graph: Example
Starts with data
in a table like this
Pie Chart/Circle Graph: Example
Reminder: the sum of the sectors must equal 100%
…is comparing parts to a whole, so a pie cart is best for this data.
Transfer the data into a circle graph like this
Parts: comedy, action, romance etc. Whole: types of movies

21. Different types of charts, tables, and graphs
Line Graphs
…are used to display data that changes over time
Line graphs allow us to see overall trends such as an increase or decrease during a specific time period

22. Transfer the data into a line graph
SPI 0807.Inq.3:
(Interpret Data)
Notes
Line Graph: Example
Science
Starts with data
in a table like this
…is not comparing parts to a whole, so a pie cart is NOT appropriate.
Transfer the data into a line graph
…is showing change over time, so a line graph works best for this data.

23. Different types of charts, tables, and graphs
Bar Graphs
are used to compare categories of items (categorical data)
…a visual display for comparing quantities in different categories  
Bar graphs help us to see relationships quickly.

24. Bar Graph: Example
Example: A survey of student's favorite after-school activities was conducted at school. This table shows the results
…is not changing over time, so a line graph is NOT appropriate.
…is not comparing parts to a whole, so a pie cart is NOT appropriate.
…is comparing categories, so a bar graph works best for this data.

25. Review Question Bar graphs are used to compare categories
Bar graphs help us to see relationships quickly.

26. Review Question Pie charts are circular charts divided into sectors.

27. Line graphs are used to display data that changes over time
Review Question
Line graphs are used to display data that changes over time

28. Line graphs are used to display data that changes over time
Review Question
Graph A shows the distance increasing over time, and it is traveling faster at the end than at the beginning. This does not match the data in the table.
Notice the trend in this data.
Every ten minutes the bus is moving further away from
the school.
Graph B shows the bus slowing down and barely increasing at the end. This does match the data in the table. So Graph B is correct
However it slows down during the last 20 min.
Correct
Speeding Up
Slowing Down

29. Review Question Pie charts are circular charts divided into sectors.
Best used for comparing parts to a whole.
