Question 1

Statistics for Business and Economics, Ch. 2

Displaying data visually helps to present the data without having to use mathematics. Using charts and tables researches are able to display data in a way that readers can understand. Often times displaying data visually also makes it easier for the researcher(s) to present. It also gives the researcher(s) more information about the data that they are presenting. When we use a histogram to display data we can see what the distribution of the data is, line charts give us information into the trend of the data, scatterplots give us information about the relationship of the variables, and tables are a great way to show the data at a glance. It is extremely important to know if data is distributed normal or not.

What is the empirical rule?

 

Question 2
