Explanation / Answer

Purpose

What is the purpose of the study?

Final Project Article - The purpose of this article is nurses work long shift and suffer sleep loss between 2a.m. and 5a.m. because of the long 12 hour shifts they work.

Reference Article - The purpose of this article is nurses work long shift and suffer sleep loss between 2a.m. and 5a.m. because of the long 12 hour shifts they work.

Research Queston(s) What is/are the research question(s)?

What causes the sleepiness of nurses? Is the results in the article correct about the lack of sleep nurses get? Are the results accurate enough through this article to determine specific factors to a better solution to the lack of sleep nurses get? Is this the only profession this happens?

Hypothesis(es) What is/are the hypothesis(es) of the study?

The hypothesis is to prove what causes the lack of sleep at night and long shifts nurse endure. The hypothesis is to prove what causes the lack of sleep at night and long shifts nurse endure.

Explanatory Variable(s) What is/are the explanatory variable(s)?

Lack of sleep at night nurses get at night.

A scatterplot is the most useful display technique for comparing two quantitative variables. We plot on the y-axis the variable we consider the response variable and on the x-axis we place the explanatory or predictor variable.

How do we determine which variable is which? In general, the explanatory variable attempts to explain, or predict, the observed outcome. The response variable measures the outcome of a study. One may even consider exploring whether one variable causes the variation in another variable – for example, a popular research study is that taller people are more likely to receive higher salaries. In this case, Height would be the explanatory variable used to explain the variation in the response variable Salaries.

In summarizing the relationship between two quantitative variables, we need to consider:

Association/Direction (i.e. positive or negative)
Form (i.e. linear or non-linear)
Strength (weak, moderate, strong)

When we consider the relationship between two variables, there are three possibilities:

Research Methods: In an observational study investigators observe subjects and measure variables of interest without assigning treatments to the subjects. The treatment that each subject receives is determined beyond the control of the investigator. For example, suppose we want to study the effect of sleep hours of nurses from 2a.m. until 5a.m.
