Creating Graphs

Types of Graphs Line Graphs Compare two variables Show trends and relationships in data Allow the viewer to make predictions Bar Graphs Visually represent a set of data Pie Charts Show part-whole relationships Used mostly in statistics

Independent Variable The factor that is varied in an experiment and specifically controlled by the experimenter Located on the x-axis

Dependent Variable The factor that is measured in an experiment and will change as a result of the independent variable Located on the y-axis

On Paper Using your data, identify the independent and dependent variables Draw your graph, labeling the x- and y-axis Title your graph Choose your intervals based on your data Plot your data

Practice-As a Class Diabetes is a disease affecting the insulin producing glands of the pancreas. If there is not enough insulin being produced by these cells, the amount of glucose in the blood will remain high. A blood glucose level above 140 for an extended period of time is not considered normal. This disease, if not brought under control, can lead to severe complications and even death.

Questions What is the dependent variable? What is the independent variable? What would you title the graph? Which individual(s) has diabetes?

Practice-In Your Notes

Questions-Type in document What is the dependent variable? What is the independent variable? What was the average thickness of annual rings for 40 year old trees in Forest A? Based on the data shown, what can be concluded about the comparative health of Forest A & B? What type of relationship (constant, direct, or indirect) exists between the age of trees and the average thickness of the tree’s rings? Explain.

On Google Sheets/Excel Go to your Google Drive Click “new” Click “Google Sheet” in the drop down menu Name your file Enter your data (x-axis in the first column and y-axis in the next column) Select your data Click “Insert” Choose the appropriate chart type based on the data Make sure your graph has a title, legend, and axis labels If not, right hand mouse click the graph to make the necessary changes

Graphing Practice Assignment In google classroom, locate the In-class graphing practice assignment Click on the assignment Create a google sheet and title: In-Class Graphing Practice Type in the data table (on the next slide) Create the appropriate graph You need to have a graph title, labeled axis, and a legend You will submit this to google classroom after we are finished

Practice-As a class Open Google Sheets Using the data, identify the independent and dependent variables Input your data (independent in first column, dependent in second column) Select the correct type of graph Make sure the graph has a title, axis are labeled, and there is a legend
