Now it is time to address these details. Specifically, this Activity addresses the 10% condition and the Large Counts condition. These two details are critical for student success when we get to inference, as they will become the conditions necessary to calculate confidence intervals and perform significance tests for proportions. The 10% condition states that sample sizes should be no more than 10% of the population. Whenever samples are involved in statistics, check the condition to ensure you have sound results. Some statisticians argue that a 5% condition is better than 10% if you want to use a standard normal model. For example, the 10% condition normally applies ... AP STAT. 5 terms. mmaxim0453. Preview.

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 ...

It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10. The formula for the z-test statistic is: z = (ˆp1 − ˆp2) − (p1 − p2) √(ˆp ⋅ ˆq( 1 n1 + 1 n2))Random Condition – random sampling was introduced in Lesson 4.1 and random assignment was introduced in Lesson 4.2. 10% condition – Lesson 6.3.

Bias refers to a systematic deviation from the true value or an unfair influence that affects the results of statistical analysis. It can occur during data collection, sampling, or analysis and leads to inaccurate or misleading conclusions. The large counts condition, also known as the "success-failure" condition, is used when applying certain ...
