Unit 4
Statistics
In this statistics unit students have the opportunity to investigate and make sense of various strategies for measures of center and spread for realistic contacts and situations. Students create and critique visual representations of data summarized in dot plots, frequency tables and histograms. In the culminating module, students choose a question of interest, collect data and present a summary of the data in a statistics project.
Students can identify and pose statistical questions and tell the difference between numerical and categorical data.
Help students solidify what makes a statistical question and how to differentiate between categorical and numerical data, and explore the mean of a data set.
Students are officially introduced to the formal method for calculating the mean, the computation strategy, in this lesson through a comparison with a pre-formal method of calculating the mean, the compensation strategy. Students are invited to practice finding the mean of a data set through the Mean Tiles game which also reinforces some executive function goals.
This lesson builds on previous lessons about statistical questions and relies on a context of a class of students going outside and kicking some soccer balls. Students will explore with a PhET simulation and discover the meaning of the median and how to calculate the median, and compare the median with the mean.
This lesson focuses on identifying the shape, center, and spread of a data set. Students will also utilize the PhET statistics sim.
This lesson focuses on organize data into frequency tables to construct histograms: describe skew and draw conclusions.
Compare data sets in histograms and dot plots to draw conclusions and make comparisons between 2 sets of data.
This lesson focuses on providing an overview of the project unit, supporting students in generating personally relevant numerical statistical questions, and gathering class data in response to these questions.
This lesson builds upon the previous lesson where students generated personally relevant numerical statistical questions and gathered class data in response to these questions. In the current lesson students will use the data gathered to construct different representations to illustrate that data. They will also engage in discussions on what they learned from the data toward answering their questions and evaluating their predictions.
This lesson guides students through the analysis of their data. Students will spend the majority of the lesson discussing their findings with their group. Then students will write their individual summary and analysis of the data in a cohesive paragraph.
Students will present their survey results to the class in their groups. Students will have time to reflect at the end of the lesson about which data they found the most interesting and if they would do anything to improve their presentation in the future.
Which One is Special? is a general-purpose activity where students think and decide which object is not like the others.
