Students review one-variable topics such as graphing quantitative variables, calculating measures of central tendency and spread, and making comparisons.
In this activity, students will review what they know about one and two variable statistics. They are given data about health indicators for some Asian and African countries.
First, students are asked to compare the three distributions that describe the percentages of people who have access to health services, safe water, and sanitation. They will create histograms and box plots and add measures of central tendency and spread.
Then, students are asked to investigate relationships between two variables, finding a positive correlation, negative correlation, and no correlation. They will also find the line of best fit and the linear regression line on one of the scatter plots. There are both general and specific questions that students will answer on the worksheet.
