In order to uncover insights in data, it is important to draw conclusions about the population that is being studied using numerical measures. In this course, you will identify various numerical measures including percentiles, range, variance, and standard deviation. You will then see how to visualize and draw conclusions on quantitative or qualitative variables. This course uses tables and charts to compare combinations of variables, identify the means of finding relationships between variables, and teaches you to interpret results and make predictions between variables.
WHAT YOU'LL LEARN
Identify numerical measures such as percentiles, range, variance, and standard deviation
Discover additional tools available to describe data, as well as means of visualizing numerical measures
Use numerical measures in your own practice
Examine how to use tables and charts to compare combinations of variables, both qualitative and quantitative
Practice creating these visual comparisons on your own
Review guidelines for effectively communicating your findings, and then create research questions that can be answered visually
Identify the means of finding relationships between variables, and then practice calculating this relationship yourself
Analyze some issues you may encounter in interpreting your results
Predict the value of one variable based on another’s value, and then make predictions between dependent and independent variables
