explain how to use the p<.o5 to determine rejection of the null hypothesis, assuming the author is using a significance level of .05

you would reject. if you refect the null hypothesis then you take the next hypothesis. it's quantitative

null hypothesis

no difference, no significance, no relationship, etc.

what type of study is designed to gather knowledge that has direct clinical application?

applied research

applied research

performed in practical setting w/ subjects that represent the group. used in most nursing research

identify the dependent variable in the following hypothesis: "exercisers exhibit higher self-efficacy scores compared to non-exercisers."

dependent: self-efficacy
independent: exercising (also population of interest in this ex)
the research is quantitative b/c we/re comparing. aka a directional alternative hypothesis

dependent variable is the _

effect

independent variable is _

what you are doing/ the cause

what do we call hypotheses that do not specify a particular direction in relation to variables under study?

a NON directional

as a general rule, level of significance do researchers most often use?
why?

.05 or 95% for nursing
higher risk for mortality

give an an example of a null hypothesis.

no difference, no correlation, etc. must be stated in the hypothesis

what sampling method is the best way to select a group of subjects if you are interested in making statements about the larger population?

random

the most meaningful research problems come from what sources

nursing practice: theory, riew lit, replication

all members of a population have an equal chance of being selected as subjects in a research project. what type of sampling is this called?

random

you decide to select a sample of 100 subjects of whom 10% will be african american, 10% hispanic, & 80% caucasian. identify the appropriate sampling design.

quota sampling

quota sampling

represent culture and ethnicity appropriately. if you attach a number it becomes quota & cant stop until you get that percent

grand theory

what is are forms of nonrandom sampling

snowball effect,
convenient sampling,
purposive sampling

describe the types of reliability

test-retest,
interrater (consistency between researchers, coding, responses, etc)
internal consistency (questions are internally consistent)

what types of criterion-related validity evidence

concurrent (happening at the same time is their validity between the 2),
predictive (how you do in testing in class will predict how you will do on nclex)

test-retest reliability focuses on the _ of an instrument?

consistency (you can do it again & again) [validity means did it answer the question you asked)

accurately describe test-retest reliability

amount of time between time test was taken. environment, etc can make a difference. it's stronger if use repeated measures of diff types (ex. test w/ stick & send it to lab for culture test or fast strep test then culture)

a variable is a measurable characteristic that varies in what

populations (population of interest)

as a nurse you rate a patients pain on a scale from "no pain" as 0 to "greatest pain ever" as 10. this results in what type of scale?

cue methodology. [Pg. 139.] ordinal-this is lowest to highest w/o equal diff. between them

what value represents the 50th percentile or midpoint of a distribution

median

there are several ways in which confounding extraneous variables an be controlled. what control technique is considered the best?

true experimental design, random assignment

what can be used for randomly assigning subjects to groups in an experimental study?

draw out of hat,
computer programs, etc

extent of burn injury

control groups in experiments are used to_

determine if the independent variable is caused by the dependent variable

the group that receives the experimental treatment condition is the _ group
