EVALUATING DATA


In this unit, you will be evaluating different types of data.  You will analyze data in tables, compare the same data in different types of graphs, investigate scatter plots and their lines of best fit, and interpret histograms.  You will determine if data is symmetrical or skewed.  You will evaluate types of biased and unbiased samples of data that is representative of a larger group and examine how data and graphs can be presented in misleading ways.
