  •  Students will  use a technology tool to display and compare  two sets of data and draw conclusions about which data set appears to display the more accurate measuring tool.
  • Students will also look at how to compare samples and make inferences based on the median and the inter quartile range (IQR) of each sample.
  • Students will classify angles of different measures such as complementary or vertical angles
