Question

The General Social Survey asked 400 randomly selected Americans the number of hours of TV they watched per day. Which of the following is the most appropriate plot for the data?

	a.	Stacked bar chart / mosaic plot
	b.	Histogram (MAYBE)
	c.	Pie chart
	d.	Scatterplot
	e.	Side-by-side box plot

Answer 1

Ans: The most appropriate plot for this data would be histogram. In theory, TV watching is a continuous variable. It can take any value from 0 to 24 including decimal values as well and therefore For such continuous variable, we can divide the interval of possible values into smaller intervals formed with values grouped together.

The advantage of doing so is that we can easily identify the most common outcome like the majority of 400 americans watches tv for how long. Also by looking at the frequencies, we can easily get an idea of percentage of people who watches television for more than a particular number of hours
