PH 516 Day 2 review

If A, B, and C are independent, then P(A, B, C) = ?

Which of the following parameters describes the population?

the value that occurs most frequently

If A, B, and C are mutually exclusive events, then P(A or B or C)= ??

\frac{λ^xc-λ}{X!}=

Quantitative synthesis of data derived from individual studies

number of individual scores that can vary without changing the sample mean. written as 'N-1' where N= number of subjects

areas under curve under normal distribution is found by using

Systematic Review is useful but when

n-1 degrees of freedom

This picture represents

A subset of the population describes

This picture represents

Z > n (when n=any number) equals

The population is first divided into relevant strata (subgroups), and a random sample is then selected from each stratum

The confidence that the mean is applicable to the population

\frac{X-μ}{σ}=

In which sample does every subject have an equal probability of being selected for the study

Quantitative or quantitative analysis

systematic random sample is one in which

H0 represents the

Outcome of one event has no effect on the second outcome defines....

This equation represents which type of distribution

"K" is determined in systematic sampling by dividing the number of items in the sampling frame by the

the number of successes X observed in n independent trials, each with the same probability of occurrence

P(O and A)= P(o) x P(A) (multiplication rule) is used for which event

The null hypothesis is represented as H1

Positivity of test

Z-score tells us how many standard deviation the original observation falls away from the mean and in which direction

If α is not given, assume it is 0.05

Arithmetic average of the observations

ONLY reject or accept the null hypothesis

Samples are quicker, less expensive, more accurate, and reduce heterogenity,

Z < n (when n is any number) =

For data that is not normally distributed (Skewed), Z-distribution can be used

Complementary event equals

What range does probability stay between

95% Confidence Interval = _______ α

What chart helps you find the Z*

Forrest and Funnel plots calculate

One outcome prevents the outcome of another

for populations, there are no population parameters

The number of times an outcome occurs over the total number of trial defines.....

P(O or A)= P(o) + P(a) (addition rule) is used for which event

What are the 4 methods of sampling

Meta-analysis is appropriate when there are ______ studies

a two-stage sampling process in which the population is divided into clusters, a random sample of clusters is chosen

In Standard Error of Mean, the Greater the N, Smaller will be the SEM

probability of rare events when the number of trials is large and the possibility of any one occurrence is very small

In confidence interval, α represents the

Systematic review is qualitative or a qualitative synthesis

If probability is close to 1, the outcome is

Literature not found in a published journal

What should you do if P-value is low

Point at which half the observations are smaller and half are larger

Specificity represents the negativity of test
