How Often do We Eat: An Introduction to Frequency Tables

In our Statistics class this week, we discussed the basic principles of Statistics, which included measures of central tendency: mean, median, mode and range. We started our unit off discussing how to find the mean, how  to create a frequency table, how to find the mean from a frequency table and then how to create a histogram and find probabilities from said histograms. To understand the idea behind these objectives, Ms. Saint-Preux polled the entire class on the following question, "How often do we eat?"

First, we polled the class to get our raw data. We then created a frequency table based on our results. From there, we calculated the average of how often our class eats. Ends up our class eats, on average, 8 hours a day!

On the next day, we discussed creating a histogram. We took the basic information of the hourly increments and our frequency to create our histogram. The results are shown here below.
