Insights+into+Data


 * Overview**
 * Section A**: In this section, the students reconnect to their 7th grade work on scatter plots. They examine clusters of data comparing each state's population and per capita income.
 * Section B**: This section focuses on the collection of "fair" data. The students complete activities that highlight the idea of random sampling, sample size, and bias.
 * Section C**: This section focuses on the critical pieces of various graphs that are used to display data. The students develop a critical "eye" for examining data as they interpret graphs that contain methods commonly used to represent data in a favorable way. The key idea is that the method used to collect, interpret, and display the data depends on the nature of the question being asked and the purpose of the study.
 * Section D**: In this section, the students review and extend their 7th grade experiences with histograms and box plots as methods to examine the distribution of data.
 * Section E**: In this section, the activities are meant to bring the student's understanding of scatter plots to a more sophisticated level. They will use the scatter plots to determine the strength of the relationship between the two variables (For example, Is there a relationship between a person's shoe size and height? Is the relationship strong or weak? Is the relationship consistent as we grow?).
 * Section F**: In this section, the students use several sets of data to make a scatter plot and then draw lines or curves to model the data. They revisit their earlier learning to determine the equation of the line in slope-intercept form.
