Frequency Table Activity 1. A researcher studies the effects of having pets on stress levels. The research typically shows that pets can significantly reduce stress. With students being under quite a bit of stress the question was "what kind of pets do students usually have"? For the following pet data the researcher collected, make a frequency table with values (X column), frequencies (f column), and percentages (% column). Then draw a bar graph and a pie chart to show two ways of representing the results. Hint... if we are counting frequencies, "frequency" and "quantity" are the same thing.

The researcher wanted a cumulative frequency of pets calculated. Complete the table below noting frequency (how many times each pet category was seen on your response to #1), the cumulative frequency, then calculate the cumulative percentages (a.k.a "relative" frequency). Start the frequency column with the SAME values you have in the f column above.
