  6. Hector’s Taco Shop Making Inferences: Use the observable data in the graph to make inferences. Hector’s Taco Shop • Hector opens his taco shop 4 days a week. The graph shows the money he made last week. • If Hector has to close his shop either Thursday, Friday, Saturday, or Sunday, what day should he close it? Why? Amount of Money Earned in Dollars

The graph shows the money he made last week. • On which night should Hector have the most food prepared? Why? Amount of Money Earned in Dollars

  8. Making the Grade! Number of Students Making all As in 4th Grade Double Bar Graph • Which group, boys or girls, had the most As? • In which quarter did the boys and girls have the same number of As? • Using your inference skills, which quarter would you infer was the most difficult quarter for the students? Why? # of Students Making all As

  9. Television Conclusions • Make conclusions about students’ ages and the number of hours they watch television on the weekends. • Example: • The older the students are, the more hours they watch television on the weekends.

  10. Making Conclusions • Using the data in this double bar graph, make a conclusion statement about the average monthly temperatures in the summer months. • Using the data in this double bar graph, make a conclusion statement about the average monthly temperatures in the winter months.

  11. Comparing Graphs to Make ConclusionsUsing the data in these two graphs, are the following statements true or false conclusions? • 5th graders always buy more milk than 4th graders. • Both 4th and 5th graders increase their milk purchases as the days progress. • The day the 4th graders bought the most milk is also the day the 5th graders bought the least amount of milk. • The day the 5th graders bought the most amount of milk is also the day the 4th graders bought the least milk.
