. Student Exploration graphing Skills Vocabulary touchst wizard chart, atmosphere graph, negative kind, pie chart, positive relationship, scale leaf, scatter plot of land, variable star Prior Knowledge Questions (Do these forwards using the Gizmo. ) 1. Four kinds of graphs are specifyn in this Gizmo. Circle the kinds you hit rendern before. picpic picpic occlude graph Line graph Pie chart disperse plot 2. Where have you supposen graphs apply? Graphs are used everywhere. You female genitals gamble them in textbooks, newspapers, meetings, schoolroom, everywhere.Basically anyplace someone needs to portray information, visualize data, display trends or patterns, compare two or more things, chart progression/digression, show relationships, etcetera 3. Why do you think graphs are useful? Like declared above, graphs are useful to share information with others and put it in a picture-like form. Sometimes it is easier to understand a concept if you can visualize it, which is what a graph does. Gizmo Warm-up Using the Graphing Skills Gizmo 1.The Graphing Skills Gizmo starts with a bar graph on the right and a data erect on the left. Practice using the Gizmo by doing the following carry finished a surname. Label the plumb and flat axes. Change the scale of the straight bloc. Drag the bars up and down. 2. Use the Graph typecast dropdown arguing to select other kinds of graphs. Practice with each type of graph On the Line graph drag the points up and down. On the Pie chart intensify the size of each slice by dragging the edges. On the dust plot drag points from the data circumvent to the graph. activity A pull in the Gizmo ready pic Bar graphs On the challenge menu, select get to graph. On the Graph type menu, select Bar graph. If necessary, click hot until Animal speed data appears. Goal number a bar graph based on a data table. 1. pass water graph A bar graph is useful for comparing things, such as how fast an imals can run. pen a designation for the graph. (Look at the title of the data table for a suggestion. ) Label the horizontal axis and the vertical axis. Pick what you think is the best choice for a vertical axis scale. Drag each bar to match the data in the table. Do your best to estimate heights. 2. cope with your acidify Click Check to see how soundly you did. A. What was your accuracy get to? everyplace 90 is excellent. ) Accuracy accounting is 100. B. What vertical scale did you choose? (In other words, how much does each horizontal line on the graph represent? ) Each line on the graph represents 20 km/h. 3. Revise Click Show economic value on mouseover. Move the cursor over each bar to see its value. Adjust each bar and click Check until the accuracy grad is 100. To show your work, click the screenshot camera at upper left. Paste the screenshot into a blank document. 4. empathize Which of these animals is fastest? Cheetah Slast-place? Human . obligate Click New and make the next bar graph. Adjust the scale if needed and dont forget to make a title and label each axis. Click Check to see your accuracy. A. What coun generate has the highest intent expectancy? The lowest? Country with the highest spirit expectancy is Andorra. Country with the lowest is Zambia. B. Does anything about the graph surprise you? I hoped that the USA would have the highest life expectancy, but that was not the case. (Too many McDonalds to blame. ) 6. Challenge yourself Hold a contest with your classmates. maturate off the Show value on mouseover checkbox and click New. Who can create the most accurate bar graph? Activity B Get the Gizmo ready pic Line graphs and pie charts Under Graph type select Line graph. If necessary, click New until Temperature data appears. Goal Build a line graph and a pie chart. Line graphs 1. realise graph Line graphs are often used to show how something changes over time. lay aside a title and label the axes. Adjust the verti cal scale if needed. take a leak the line graph by dragging the points up and down. 2. Check your work Click Check. What was your accuracy print? Accuracy score is 100. 3. Revise develop on Show values on mouseover and adjust the graph until your score is 100. Take a screenshot of your graph and paste it into a document. 4.Interpret Which mean solar day was hottest? Wednesday Which day was coolest? Sunday 5. Apply show additional line graphs until you are satisfactory making this type of graph. Discuss the most interesting graphs with your teacher and classmates. Pie charts 6. Create graph Pie charts are used to show proportional data. Under Graph type select Pie chart. Make sure that Show values and labels is checked. Write a title for the pie chart and drag the pie pieces to match the data table. 7. Check your work Click Check. Revise your pie chart if necessary.When the pie chart is correct, paste a screenshot of the chart into your document. 8. Interpret What were the most popular pies? Apple 9. Apply Try additional pie charts until you are comfortable with this type of graph. For a real challenge, try to make a pie chart with the Show values and labels checkbox turned off. 10. cast up your thinking The Gizmo also allows you to create a data table from a graph. Under Challenge select Create table. Write a title for the table and then fill in each change box based on the graph. Click Check to check your accuracy. Activity C Get the Gizmo ready pic Scatter plots Under Challenge select Create graph. Under Graph type select Scatter plot. If necessary, click New until Studying and score data appears. Goal Create a scatter plot. 1. Create graph Scatter plots are used to see if one variable is related to another. Each point on a scatter plot has two values. For example, if Robert studied for 40 proceeding and got a quiz score of 98, Roberts point would be put at (40, 98) on the graph. (You can think of that as over 40, up 98. ) To make a sc atter plot, do the following Write a title for the graph. Label the horizontal axis based on the sustain column of the data table, and the vertical axis based on the ternary column of the data table.Include units in each label. Adjust the horizontal and vertical axis scales if needed. Drag each point to match the data. 2. Check your work Click Check. What was your accuracy score? Accuracy score is 100. 3. Revise Turn on Show values on mouseover and adjust the graph until your score is 100. Adjust the axis scales if necessary. Paste a screenshot of your graph into a document. 4. Interpret Based on this graph, will studying help you do well on a test? Explain. Yes The longer a student studied, the high his/her test score was. 5. Extend your thinking The Studying vs.Score scatter plot shows an example of a positive relationshipas one variable increases, so does the other. The points in this type of scatter plot tend to go uphill from left to right. A negative relationship is the oppositeas one variable increases, the other variable decreases. These types of scatter plots go downward-sloping from left to right. A. Which graphs in the Gizmo show a positive relationship? In the Income versus Education graph, as ones education modify and increased, the income they earned also increased. With the Study and Score Evaluation, when ones study time increased, the score also correlated with an increase.With the Growth Over Time graph, there is a positive relationship since as one person increases in age, the height also increases. B. Which graphs in the Gizmo show a negative relationship? The only graph I could find which remotely represented this was the Temperature Data Graph. As progression increased through the week and it got closer to the weekend, the temperature decreased. Although not demonstrated in the Gizmo, a double-dyed(a) example of a negative relationship would be as the cosmetic surgery above sea level rises, the temperature decreases. pic
