Types of test Flashcards
1
Q
chi squared test
A
- independent analysis of two sets of independent categorical data
- must meet the assumptions
2
Q
one sample t-test
A
- test of a mean
- normal distribution
- unknown population SD
- small sample size
3
Q
paired t-test
A
- dependent data
- one sample and repeated measurements
- differences are plausibly normally distributed
4
Q
binomial test
A
- comparing a proportion/percentage for a sample against a population value
- a normal approximation can be used when np>5 and n(1-p)>5
5
Q
mann whitney u test
A
non parametric independent samples
6
Q
testing of a mean using the normal distribution (one sample z-test)
A
- when population SD is known
- sample size over 30
- normally distributed
7
Q
sign test
A
- test of median of a single sample
- can test differences between paired data
- very quick
8
Q
wilcoxon signed rank sum test using the z statistic
A
- large sample size
- non parametric
- test median of a single sample or the difference in a paired sample
9
Q
independent t test
A
- independent samples
- plausibly normally distributed
- comparable sample variances
10
Q
Wilcoxon signed rank sum test using W statistic
A
- test of a median of a single sample, or the difference in medians of a paired sample
- non-parametric
- small sample size
