what is nominal data:

Categorical (MenWomen), (Family Practice, Internal Medicine, Pediatrics), (A,B,AB,O)
data that you can count but not order or measure 

what is ordinal data:

implied order between categories: (Stable Serious Critical) (Stage I II III cancer) (very satisfied to very dissatisfied)


what is interval data:

infinite values, can subtract values: (Continuous) (Discrete)
height, weight, blood pressure 

match the type of average with the correct type of data:
... data – Mean ... data – Median ... data  Frequency 
Interval
Ordinal Nominal 

Ho represents the ... hypothesis

null


what does this describe:
Chance – Really no difference between the groups 
The NULL Hypothesis


what does the following describe:
Something is Going on here (The Pill Works) 
The Alternative Hypothesis


H1 represents the ... Hypothesis

Alternative


what does the following describe:
Mathematically equivalent to 0 or 1 depending on the level of measurement 
NULL statement


what are the 2 different types of decision methods we discussed in class:

decision point method
confidence interval 

This decision point will be measured by the ... This translates into the probability of what we see is due to chance alone

pvalue


If the pvalue is large, it favors ...
If the pvalue is small, it favors ... 
Ho
H1 

for most published articles p < ...
for drug trials p < ... or p <... 
.05
.01 .001 

The probability of rejecting the null hypothesis when you should not is what type of error

type I


what is the marker for the null hypothesis when the results are in a ratio form (relative risk or odds ratio) ...

1 represents Ho


the Pvalue that researchers decide to accept before they will be confident enough to release a finding. This is their predetermined acceptance level. The alpha level is not calculated, it is chosen by the researcher(s)

the alpha level


what is the marker for the null hypothesis when the results are in an interval form ...

0 represents Ho


If the probability of the results of the statistical test are greater than α, (p > .05) then the results (are/are not) statistically significant. we must (accept/reject) the null hypothesis

are not
accept 

If the probability or the results of the statistical test are less than α (p < .05) then the results (are/are not) statistically significant. we must (accept/reject) the null hypothesis

are
reject 

p > α Then p is large
Accept/Reject Ho 
accept


p < α Then p is small
Accept/Reject Ho 
reject
