Chi-square test. Significance test for categorial data (counts); 3 TYPES: (1) Goodness of fit, (2) Homogeneity, (3) Independence) Chi Square Goodness of Fit (GOF) ONE categorical variable from ONE population; WHEN TO USE: determine whether sample data are consistent with a hypothesized distribution. CALC: χ^2GOF-Test.They just need to put them together. Here is a list of all the pieces: Normal distribution calculations - Lesson 2.2. Random Condition - random sampling was introduced in Lesson 4.1 and random assignment was introduced in Lesson 4.2. 10% condition - Lesson 6.3. Large Counts Condition - Lesson 6.3. Sampling distribution of a sample ... State appropriate hypotheses and compute the expected counts and chi-square test statistic for a chi-square test for goodness of fit. State and check the Random, 10%, and Large Counts conditions for performing a chi-square test for goodness of fit. Calculate the degrees of freedom and P-value for a chi-square test for goodness of fit. The standard deviation of the difference is: σ p ^ 1 − p ^ 2 = p 1 ( 1 − p 1) n 1 + p 2 ( 1 − p 2) n 2. (where n 1 and n 2 are the sizes of each sample). This standard deviation formula is exactly correct as long as we have: Independent observations between the two samples. Independent observations within each sample*.AP Statistics - PHACTS. when. - there is random sampling. - the 10% condition is satisfied, - the large counts condition is satisfied: z = (p̂ - p0)/sqrt (p0 (1-p0)/n) Click the card to flip 👆. one sample z interval for the population proportion.

Help students recognize two ideas: The greater the sample size, the closer the Normal approximation is to the binomial distribution. The closer that p is to 0.5, the more symmetric the binomial distribution, and therefore closer to Normal. These two ideas are combined to form the Large counts condition np > 10 and n (1 - p) > 10.
