My EPPP Statistics and Research Design

Alpha (α) represents the significance level in hypothesis testing—the probability of committing a Type I error by rejecting a true null hypothesis. Commonly set at 0.05 or 0.01, it defines the threshold for statistical significance in research. The chi-square test is a nonparametric statistical method used to assess the association between categorical variables. The single-sample version compares observed frequencies to expected frequencies, while the multiple-sample version evaluates relationships across two or more variables.

how to do geometric probability
Example: Determine the probability of producing 3 cars before finding a defect if the probability of a defect is 1%. The formula for geometric distribution probability is: P(x) = (q^x) (p) where x is the number of failures before the first success, p is the probability of success and q is the probability of failure P(x) = (q^x) (p) = 0.99^3 (0.01) =0.0097 The probability is 0.0097 or 0.97% chance of finding a defect
