Bellringer 11/011) a) What axis is the dependent variable on?

b) What axis is the independent variable on?2) If you were given a table, how would you know

what was the independent variable3) What should be at the top of every graph? (how

do you write this?

Analyzing GraphingIf you are good (less than four names on the board), the class can earn candy at

the end of class.

Analyzing GraphsThe past few days we have seen

many graphs and even made some.Objective: Achievers on the ROAD to

college will be able to use (analyze) these graphs to give you information you need.

1) Identify The type of GraphsThere are 3 Types of Graphs

(1)Line Graphs(2)Bar Graphs(3)Pie Charts(3.5)Tables

2) Identify VariablesIdentify the Independent and

Dependent VariablesFor Bar Graphs:The (4)Independent Variable is

on the x-axisThe (5)dependent Variable is

on the y-axis

2) Identify VariablesIdentify the Independent and

Dependent VariablesFor Line Graphs:The (6)independent variable is

on the x-axisThe (7)dependent variable is

on the y-axis

Find the Independent/ dependent Variables

Find the Independent/ dependent Variables

3) Read the QuestionThere are 3 things you may have to

find in a question:Tell something about the graph:

(8)Just pick out information•How many 5th graders like Grapes?

•How many 6th graders like apples?

Make a prediction: You will not have the number you need on the graph, (9)you will have to find it out on your own

3) Read the Question

How many guppies will there be if it is 30 degrees?

Draw a conclusion: From the graph you’re going to have to be able to tell what is happening

As the (10)INDEPENDENT VARIABLE increases/decreases the (11)DEPENDENT VARIABLE increases/decreases

3) Read the Question

Duckweed is a plant that grows on the surface of ponds. Duckweed has leaf-like structures called fronds. A student conducts a lab investigation on duckweed growth and creates the graph shown above. Which of these is a valid conclusion based on the data from this investigation?

A. The number of fronds more than doubled between Days 2 and 4.B. The number of fronds increased quickly because the plant has a short life span.C. The number of fronds is related to the number of hours of sunlight each day.D. The number of fronds increased at a constant rate between Days 1 and 5.

II) Tables:Eliminate Constants: (12)Cross them out

in the graph If the (13)numbers are not changing

CROSS THEM OUT! They are Constants or controls

There is little information to gain if the numbers stay the same!

the (16)DEPENDENT VARIABLE to happen

Typically the IV is going to be in (17)even increments like: 2,4,6,8 or 3,6,9,12 or 5,10,15,20 Typically the DV is going to be (18)a lot of weird numbers

Worms under a rock

A scientist studied 5 different types of soil and counted the number of worms living in each type. Her results are shown in the bar graph above. Which statement best describes the scientist’s results?

A. Worms have similar frequencies in these types of soil

B. Worms were most often found in the muddy soil habitat

C. Worms are suffocated by clay soilsD. Worms search for moisture in sandy and loamy

soil.

Practice: Graphs

Flightless Mormon crickets often move in large groups. The graph shows the survival rate of crickets moving in large groups and of some crickets that were moved away from the groups. Which of these inferences about Mormon crickets is most likely accurate?

A. Mormon crickets within a group survive only two days.B. Mormon crickets away from a group successfully reproduce.C. Mormon crickets away from a group return to it for protection.D. Mormon crickets within a group are less likely to be eaten by predators.
