WGU C955 Applied Probability and Statistics Problem-Solving Exam Questions and With Distinction level Marking scheme updated 2024/2025 Correlation coefficient - correct answer a measure of the linear relationship between two attributes. The numerical value demonstrates how closely the attributes vary together. Correlation coefficients near -1 and +1 have strong linear correlation, while a correlation coefficient near 0 has weak (or no) linear correlation. Correlation - correct answer an ob...

AP Statistics Question and answers 2023/2024 verified to passStatistical Significance - correct answer An observed effect too large to attribute plausibly to chance. Non-Response Bias - correct answer Bias introduced to a sample when a large fraction of those sampled fails to respond. P-Value - correct answer found by substituting the x-value in the regression equation; they're the values on the fitted line Empirical Rule - correct answer A statistical rule stating that for a normal di...

AP Statistics Vocabulary List Study Guide Exam Questions 2024. Statistical Significance - correct answer When your discovered p-value is less than your alpha (.05 if not given). States that chance alone would rarely produce an equally extreme result. Non-Response Bias - correct answer A bias caused by a number of people who did not respond to the survey. p-Value - correct answer The probability of getting a result at least as extreme as the result given from the test. The lower the value ...

Statistical Significance correct answer: When your discovered p-value is less than your alpha (.05 if not given). States that chance alone would rarely produce an equally extreme result. Non-Response Bias correct answer: A bias caused by a number of people who did not respond to the survey. p-Value correct answer: The probability of getting a result at least as extreme as the result given from the test. The lower the value the stronger the evidence. Empirical rule correct answer: St...
