Large Counts condition - Suppose that a count χ of successes has the binomial distribution with 𝑛 trials and success probability 𝑝. AP Statistics Unit 10 Comparing Two Populations or Groups. We use when estimating a difference in two proportions. No hypotheses are required. Uses random and large counts conditions. "P1 - P2 is the true difference in proportion of___". The conditions are random and large counts. To meet the condition of Large counts for any X^2 Statistic. When specifically does one use a T-test and a chi-square test. A t-test is used to determine the difference between two sets of data. A chi-square test involves looking for a relationship (homogeneity, independence, or goodness-of-fit.)Study with Quizlet and memorize flashcards containing terms like Distribution, Sampling Distribution, A population has ____ possible sampling distributions and more.Name: _ AP Statistics Handout: Lesson 6.3 Topics: conditions for sampling a proportion - random, 10%, large counts Lesson 6.3 Guided.

It can occur during data collection, sampling, or analysis and leads to inaccurate or misleading conclusions.

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.Chapter 10 & 11; AP Stats. Term. 1 / 58. Random, 10%, Large Counts. Click the card to flip 👆.
