Large counts condition ap stats

The Large Sample Condition: The sample size is at least 30. Note: In some textbooks, a “large enough” sample size is defined as at least 40 but the number 30 is more commonly used. When this condition is met, it can be assumed that the sampling distribution of the sample mean is approximately normal. This assumption allows us to use samples ...

Flashcards; Learn; Test; Match; Q-Chat; Flashcards;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.)Assumption #2: Independence. Each observation in the sample data should be independent of every other observation. This means that no two observations in a sample are related to each other or affect each other in any way. If you use a random sampling method to collect the data, this assumption is typically met.Large Counts Condition: The large counts condition, also known as the "success-failure" condition, is used when applying certain statistical methods to categorical data. It states that for these methods to be valid, both the number of successes and failures must be at least 10.Study with Quizlet and memorize flashcards containing terms like The sampling distribution of x bar tells us how ... the µ the sample mean x bar is likely to be, A C% confidence interval gives an interval of, All confidence intervals are constructed have a form of and more.10% condition: n ≤ (1/10)N: 16: 5831492206: Large Counts condition: np>=10 and n (1-p)>=10: 17: 5831504460: Geometric Setting: arises when we preform independent trials of the same chance process and record the number of trials it takes to get one success, 4 conditions must be met (BITS) 18: 5831511288: T in BITSAP Stats Unit 9.

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. Random Condition: so we can generalize to the population. 10% Condition: so sampling without replacement is OK. Large Counts: so the sampling distribution of the sample proportions will be approximately Normal and we can use z* to do calculations.
