What 5 formulas are used for the Difference of Proportions Test Calculator?
p^1 = x1/n1
p^2 = x2/n2
q^1 = 1 - p^1
q^2 = 1 - p^2
(p^1 - p^2) - zα/2*I < p1 - p2 < (p^1 - p^2) + zα/2*I
p^2 = x2/n2
q^1 = 1 - p^1
q^2 = 1 - p^2
(p^1 - p^2) - zα/2*I < p1 - p2 < (p^1 - p^2) + zα/2*I
What 7 concepts are covered in the Difference of Proportions Test Calculator?
- alternative hypothesis
- opposite of null hypothesis. One of the proposed proposition in the hypothesis test.
H1 - confidence interval
- a range of values so defined that there is a specified probability that the value of a parameter lies within it.
- difference of proportions test
- hypothesis
- statistical test using a statement of a possible explanation for some conclusions
- null hypothesis
- in a statistical test, the hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.
H0 - proportion
