This document contains more than 250 comprehensive exam questions and answers for NURS 5366 Week 5 Nursing Research Statistics, covering descriptive statistics, probability theory, normal distribution, measures of central tendency, validity and reliability testing, hypothesis testing, chi-square analysis, sample size, effect size, and power. Across 28 detailed pages , the material systematically reviews mean, median, mode, range, standard deviation, frequency distributions, probability distributions, sampling distributions, z-scores, skewness, kurtosis, and the characteristics of symmetrical and asymmetrical curves.
The content provides in-depth explanations of the normal curve, alpha levels (.05, .01, .001), type I and type II errors, null and alternative hypotheses, decision theory, one-tailed versus two-tailed testing, and interpretation of statistical significance. It also covers measurement tool evaluation including content validity, convergent and divergent validity, reliability (internal consistency, inter-rater reliability, stability, homogeneity, equivalence), sensitivity, specificity, positive and negative predictive value (PPV and NPV), and screening test accuracy using 2x2 tables.
Additional sections address chi-square testing for nominal and ordinal data, degrees of freedom (including 2x2 table rules), Fisher’s exact test, Yates’ continuity correction, McNemar test, effect size interpretation, power analysis calculations, and the relationship between sample size and statistical power. Practical examples illustrate probability applications, clinical screening test evaluation, and statistical reasoning in nursing research design.
This resource is especially relevant for students enrolled in:
NURS 5366 Nursing Research
Graduate Nursing Research Methods
Evidence-Based Practice and Biostatistics courses
MSN core curriculum research modules
DNP quantitative research foundations
It is ideal for graduate nursing students preparing for statistics-focused exams, midterms, and comprehensive research methodology assessments.
The content aligns closely with standard graduate nursing research textbooks such as Nursing Research: Generating and Assessing Evidence for Nursing Practice by Polit and Beck, particularly chapters addressing descriptive and inferential statistics, measurement validity and reliability, hypothesis testing, chi-square analysis, and statistical power in research design.

Chapter 3 - 🧠 ANSWER ✔✔DESCRIPTIVE STATISTICS, PROBABILITY,
AND MEASURE OF CENTRAL TENDENCY
descriptive Statistics - 🧠 ANSWER ✔✔computed to reveal characteristics of
the sample and to describe study variable
,How to describe a sample - 🧠 ANSWER ✔✔create a frequency distribution
of the variable or variable being studied
- is a plot of one variable, whereby the x-axis consists of possible values of
that variable , and the y - axis is tally of each value
Inferential Statistics - 🧠 ANSWER ✔✔computed to draw conclusions and
make inferences about the greater population, based on the sample data
set.
Bi Modal - 🧠 ANSWER ✔✔having or providing two modes, ,methods,
systems, etc.
-having 2 values/categories that have highest occurrence and are equal
frequencies
Central Tendency - 🧠 ANSWER ✔✔indicator of center of data
-nominal variable= categorical differences EX: gender (tendency of
samples of given measurement to cluster around some central value.
Measures of Central tendency are descriptive statistics.
, Statistics represent measures of central tendency are mean, median and
mode (all are representations or descriptions of the center or middle of a
frequency distribution
mean= arithmetic average of all of the values of a variable.
median= exact middle value ( or average of the middle two values if there
is an even number of observations)
mode= most commonly occurring value in a data set. can have more than
one mode in a sample.
in a normal curve, mean, median and mode are equal or approximately
equal
Multimodal - 🧠 ANSWER ✔✔having more than 2 modes
Unimodal - 🧠 ANSWER ✔✔When distribution only has one mode
-the frequencies progressively decline as they move away from the mode.
Symmetrical distributions are usually uni modal.
bimodal - 🧠 ANSWER ✔✔means you have not defined your population if
you find a bimodal
