Mouse Experiment An experiment studies the effects of an experimental drug on the number of offspring a mother mouse has. · Define categorical and numerical data for students for students notes. The kinesthetic aspect of this graphing activity captures the attention of the students who are kinesthetic learners which in turn improves effort and the level of student learning. · The reason it is important to know what kind of question we are asking is because it will affect our decisions about how we will organize the data and how we will organize, analyze and display the data later on in our process. · How many brothers do you have?.Next
The students will engage in a whole-class discussion to review the correct responses. When I ask a numerical question, I notice that the answers are always numbers. Which food shows a positive correlation between sales and temperature? · Categorical and numerical data often differ in the way they are organized, analyzed and displayed. · When we ask questions to generate data we usually answer them in one of two ways. · Think aloud how to tell the difference.Next
It is imperative that students know, understand, and can apply the five components of a graph. Sample questions include reading a scenario and determining which graph best represents the situation. Their weights are recorded below. By setting up multiple stations around the room, students will maximize their instruction time by keeping students engaged throughout the entire lesson! Conversely, in another example students will be shown a graph, they will analyze the curve, and then develop a statement best summarizing what has occurred. The following data was taken on nurse sharks. Their enthusiasm was contagious and set the tone for the whole activity! Use a different color to graph the nurse shark population on the graph above.
Summarize your graph in a single sentence. A positive correlation occurs when one set of values increases, so does the other set of values. Make sure you label the X and Y axis. · What is your favorite school subject? Tiger Shark Population The population of tiger sharks off the coast of Florida was recorded over several months. To learn more about this lesson, click on the Lesson Reflection below. At what month would you expect the number of nurse sharks to equal the number of tiger sharks? Students are reminded that data analysis is the most important aspect of scientific research and that scientists are reliant on proper graphs to represent their achievement and discoveries! According to the graph, which group of organisms has the most number of species? How could a park manager use this type of information? Guided Practice: 5 mins · Students will categorize given questions into categorical or numerical. By actively engaging in the station rotation strategy, students take ownership in the activity and work in collaborative groups.Next
Month April May June July Aug Bessie 100 lbs 210 lbs 260 lbs 320 lbs 400 lbs Bertha 100 lbs 250 lbs 290 lbs 340 lbs 400 lbs Graph the data; use a dotted line for Bessie and a straight line for Bertha. · Categorical questions are those that produce answers that are categories or words · Numerical questions are those that produce answers that are numbers. The number of nurse sharks was also recorded for this time period; though the person recorded the number was not as reliable as the person recording tiger shark numbers. Students will have one more opportunity practice graphing sample data before we progress on from our Data Analysis Unit. The graphing activity will take 30-40 minutes so the students must remain watchful of the time in order to complete the task before the end of the class period.Next
When students complete their station, they will look to find an open station and begin work right away. Bessie receives the experimental feed, and Bertha receives regular corn feed. Students enjoy the opportunity to independently move around the classroom and visit each station. We are going to spend a lot of time in the unit focusing on how to analyze data with statistics but today we are going to start by categorizing data and thinking about ways we gather data. · For student notes, draw t-chart for categorical v.Next
· What is your favorite color? March - 60 April - 52 July - 38 August - 20 November- 14 December - 11 a. Opening: 5 mins · Open the unit by explaining that we are going to be looking at the Four step process to approaching data · Over the course of the unit we are going to gather data, organize it, analyze it and display it. What is the total percentage for all invertebrates? Number of Babies in Litter Group A drug 5 6 4 8 5 2 7 13 12 8 Group B control 4 4 6 6 5 6 4 7 5 3 Based on the data, what would you conclude about the drug, did it work? What does the graph tell you about the trends both shark populations? Cow Growth Rates A type of feed claims to boost the growth rate of cows. Students will use to analyze the provided data and construct the appropriate graph to most effectively represent the data from the sample experiment. In tonight's , students will need to be able to read the provided prompt and decide which type of graph will best represent the data. Students will be graphing throughout the year in future units of study, but this is the last opportunity for students to practice graphing in this review unit. This is different than when I ask a numerical question.Next
The feed is tested on two twin newborn cows. This video clip captures two students working to determine which sample graph correctly illustrates the scenario in the question. The students will receive many verbal reminders as time passes to help gauge their progress and increase their chances of completing the activity before the end of the class period. · Students will be prompted to create categorical and numerical data questions. The number of mice in their litters is compared to the litters of mice that did not take the drug. Graph the tiger shark populations below.
