Using closed-ended questions may provide which advantage? What type of question is: “How often do you take naps during the day? Would you say (a) Never, (b) Rarely, (c) Occasionally, (d) Often, or (e) Almost every day?” A nurse researcher develops a multidimensional measure of nurses’ self-esteem and then gathers data to test the dimensionality of the instrument.

In the following research question, what would correspond to the “C” component in the PICO scheme? “What is the relationship between pregnant women’s smoking behavior and infant birth weight?” ...

Which statement about sample size in qualitative research is true? A nurse researcher studied barriers to smoking cessation among pregnant women. The study involved in-depth interviews with 16 women who differed in terms of marital status, parity, education, and length of time as a smoker. Which sampling method was used? A nurse researcher conducted a study of 30 women with breast cancer. In a follow-up round of data collection, the researcher focused on 10 of the women who p...

Simple linear regression is used for which purpose? A researcher tests the hypothesis that men and women differ in the amount of time (number of hours) they spend exercising weekly. Which statistical test might the researcher use, assuming a reasonably normal distribution of values?

What is the first step in scale development? For a distribution of scores on a quality of life scale, the standard deviation was computed to be 4.0. What is the value of the variance for this distribution? Which measure of central tendency is the most stable? What does a domain sampling model within the classical test theory framework assume? Which criterion is popular for putting a halt to factor extraction in exploratory factor analysis? For a ...

Which criterion is used to solve equations in a standard regression analysis? What are degrees of freedom? A researcher tests the hypothesis that men and women differ in the amount of time (number of hours) they spend exercising weekly.

What term is used for a contaminating factor in the context of quantitative studies? A researcher recruits participants for a study and advises them that their time commitment will be 45 minutes in a single session. Participants are not told at the outset that the researcher plans to collect more data from all participants 6 months later.
