Exam 20: Quantitative Research Designs: Defining Variables and Their Relationships With One Another

Please match the following definitions. -An effort dedicated to improvement of randomized controlled trial (RCT) design and RCT reporting, providing a checklist of essential items that should be included in a RCT and a diagram for documenting

Please match the following definitions. -A design where the independent variables are administered to all randomly determined groups in a sequential order

A cohort design is implemented to follow a group over time utilizing repeated measures at certain intervals.

Please match the following definitions. -A design in which groups of different types of persons, in terms of some immediate measureable dependent variable (e.g., age, presence of disability), are compared in response to exposure to an independent variable

In descriptive research, the incidence is the number of new cases of a disease or disability in a population during a specified time period.

Which of the following is not a step of a basic experiment?

In descriptive research, the prevalence is the percentage of people who have a particular health-related condition.

In descriptive research, a developmental study is conducted to:

The biggest danger to scientific development is to report a relationship that does not exist. This is considered a type II error.

Please match the following definitions. -An experiment where an important health outcome is the dependent variable, a clinical intervention is part of the independent variable, and research participants are recruited and randomly assigned over time as they become available

Correlational research seeks to find usual or average values for specific variables, thus serving as a basis to evaluate and compare an individual against a similar group.

The possibility of failure to find and report a relationship among variables in a study when the relationship actually exists is a type I error.

All of the following statements are true regarding type I errors except:

Please match the following definitions. -A design utilized to find out if some specific variable from the past discriminates between people who have a disease (or disability) and people who do not

Descriptive quantitative research depicts naturally occurring events or characteristics of research participants to generate new insights through an inductive process.
