Step 4: Select one of the articles found through the search and be sure that a frequency distribution is shown somewhere in the article. If possible, use “full text – PDF” option to glance through it. A frequency distribution will have numeric classes such as 0-9, 10-19, 20-29 and so on. It will not have classes such as female and male. Be sure the classes are numeric. The frequency may be presented as a table or a graph, either is fine.
Step 5: Type answers to the following questions on your lab Word document:
What search term(s) did you use and why did you decide to use that search term? Include how many articles were found and the full APA citation of the article you are using for this lab.
What data are shown in the frequency distribution and why might it be of interest? Include the size of the classes, noting if they are of a consistent size or not. Also include a conclusion that could be made from the frequency distribution. (1 to 2 paragraphs)
