Steps to Complete Week 3 Lab

Step 1: Go to the Chamberlain Library at: https://library.chamberlain.edu (Links to an external site.) .

Step 2: Click Databases in the Search the Library block. Then choose ProQuest Nursing and Allied Health Database in the dropdown menu.

Database Search Example

Step 3: Below, you will find the titles of six articles from the ProQuest database that show a frequency distribution within the article. CHOOSE ONE OF THE ARTICLES FROM THE LIST BELOW. You will perform two searches using this article.

For our first broad-based search, use the underlined words in your chosen article to search and see how many articles from the database contain these underlined words (see the example below the article list for an example search on post-partum depression).

Article Titles

Oral manifestations in diabetic patients under treatment for ischemic heart diseases: A comparative observational study

Systolic blood pressure , diastolic blood pressure, and pulse pressure: An evaluation of their joint effect on mortality

Example of search on post partum depression

Make sure to checkmark Full Text and Peer Reviewed, and choose Last 12 Months from the drop down list. Also, choose English under the language section.

This will yield a list of articles about the topic that you chose. Look to see how many results were found.

For our second more narrow search, go back and search for the title of the article that you chose originally. Type A PORTION of the article title into the search bar and find the full PDF for that article.

Step 4: Complete your lab by taking the following steps

Copy and paste, or post a screen shot of the frequency distribution from the article you chose at the top of your Word document.

On your first search, what terms did you use, and what other things did you mark on the search page before conducting your search? Why did you choose the article that you did? How many articles were found with these search terms? Give the full APA reference 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)

How else might these data have been displayed? Discuss pros and cons of 2 other presentation options, such as tables or different graphical displays (1 to 2 paragraphs)

Step 5: Be sure your name is on the Word document, save it, and then submit it under “Assignments” and “Week 3: Lab”.
