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

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.

SPI 0807. Inq. 3 Science Notes (Interpret Data) Different types of charts, tables, and graphs Data Tables ØTables are used to organize and display independent variable and dependent variable information/data. Independent Variable Dependent Variable

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

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

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

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

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

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

Bar Graph: 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.

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

Pie charts are. Review circular charts divided into sectors. Question Best used for comparing parts to a whole. The total amount should equal 100%.

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

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. However it slows down during the last 20 min. 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 Correct Speeding Up Slowing Down

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