Block 7: Epidemiology 3 - AppliedBiostatistics
P-cost - ANSProbability of obtaining extra "excessive" values than the located take a look at
statistic, deliver the null hypothesis is real.
Definition of "severe" relies upon on the course of the alternative speculation
zero ≤ p-price ≤ 1
P-value calculation for two-sided check
Ex: H0: 𝜇 = forty six vs. H1: 𝜇 ≠ forty six - ANSP-fee = 2*prob (T ≥ test
Ex: H0: 𝜇 = forty six vs. H1: 𝜇 > 46 - ANSP-fee = prob (T ≥ 𝑡_𝑜𝑏𝑠)
(Tail at the proper)
Left-sided take a look at
Ex: H0: 𝜇 = 46 vs. H1: 𝜇 < forty six - ANSP-cost = prob (T ≤ 𝑡_𝑜𝑏𝑠)
(Tail at the left)
Confidence interval - ANS-A range of numbers
-Always comes with a self belief level (ex: 95%)
-Need to compromise between confidence and precision: i.E. Excessive precision (slender
width) comes with low self assurance, and vice versa
Confidence c program languageperiod choices - ANSIf the 95% CI includes the null price, then
we can't reject 𝐻0. Otherwise, reject 𝐻0.
Cohort look at or RCT, use RR
Case-control observe, use OR
Statistical importance tells us: - ANSHow likely we would observe a sure facts given the null
