Index Graph: consists of 4 quadrants that each represent a combination of relative strengths and weaknesses as indicated by the prompts of the graph compass.
Really good for comparing two variables at once. Best with categorical data.

Scatter graphs: provide an assessment of the relationship of multiple elements to the ideal provided condition at the center of the circle.
Each concentric ring represents an order, from most to least related to the central theme.
Really good for looking at one continuous variable

Bubble Chart: A bubble chart is used to visualize a data set with two to four dimensions.
The first two dimensions are visualized as Size, then Color. The 3rd & 4th dimensions can be visualized as coordinates
Best with continuous data

How do different types of graphs help us see and understand plant strategies for reproduction?
Pre-think: How do plants reproduce? In what ways do plants have different strategies for their reproduction?

Types of Plants We’ll Be Thinking About

-Number of seeds per fruit
-Amount of fruit per plant
- Weight of seeds (in grams)
- Taste of fruit surrounding seed
- Seed dispersal method
- Plant life cycle
What kinds of variables are each of these?
Variables we’ll be working with for each plant
![Page 13: Analyzing & Interpreting DATA](https://reader036.vdocuments.net/reader036/viewer/2022081418/56816456550346895dd62345/html5/thumbnails/13.jpg)
-Continuous Data can take any value
-Example: Plant Height (measured in feet)
- Heights could be 2’8’’, 4’2’’, 8’3’’, 15’, 80’, etc, etc, etc.
Continuous v. Categorical Data
![Page 14: Analyzing & Interpreting DATA](https://reader036.vdocuments.net/reader036/viewer/2022081418/56816456550346895dd62345/html5/thumbnails/14.jpg)
-Categorical Data can only take certain values (within a given range):
-Example: Plant Height (categorized)
- Heights could be Short, Medium, or Tall.
Continuous v. Categorical Data

Each group assigned 1 graph type (Double Axis, Scatter, or Bubble)—2 groups work on each type of graph
Make at least 2 graphs using plant data of their choice
Include in your graphs:
What kinds of variables(data) you used (continuous or categorical)
Which graph was the most telling
One pattern you notice in your graph of choice and the relationship you predict is happening

“I notice…”“One pattern I notice
is…”
“I wonder…”
“The _______ graph helps me to see________.”
“I would like to have more information about ______.”

What patterns did you notice and what graphs helped you see those patterns best?
What information do you need to feel more confident in the relationships you see?
What are some strategies for plant reproduction based on these data?
What kinds of graphs are best for what kinds of data?

Learning objectives:
SPOTTeachers will be able use to new and different graphsTeachers will see how different graphs can reveal different patterns and relationships
Content goalTeachers will be able to identify several strategies for plant reproduction based on evidence from a data set

Analyzing & Interpreting Data, Indicator 1:Display data in table and graphs to reveal patterns that indicate relationships
Indicator Focus of Observation
3rd grade level 4th grade level 5th grade level
Display data in table and graphs to reveal patterns that indicate relationships
StudentEnter data into table or graph provided by
teacher or curriculum
Create a graph with support, and use it to display data
Decide on an appropriate
graph. Create it. Then use to display data.
TeacherProvide graphs or tables and model how to enter data
Model how to create a graph or table and how to enter
data
Model how to choose an
appropriate graph based on the activity or data collected

Where are there natural places in your upcoming lessons that students can analyze and interpret data?
Where are there shifts you can make in your upcoming lessons to allow students to analyze and interpret data?
Some prompts to help you think about your data:• How will you be collecting data?• What kind of data will you be collecting or using
(continuous or categorical)• What kinds of graphs might be best to represent the kind
of data that you are using?
