Question
In an SPSS output for Analysis of Variance for each independent variable F-statistics and Level of Significance of F is computed. Assume the level of significance for a given variable is 0.0000. Which of the following is true: a) this variable was constructed and division by zero was involved b) this variable had a significant impact on the dependent variable c) this variable has a negligible impact on the dependent variable d) this variable should be deleted and analysis re-run e) none of the above, see my essay
In case of stratified random sampling the stratas should contain units similar in terms of studied characteristic. a) True b) False
The degree of sampling error that is expected and planned for in a study is represented by: a) a statistic b) an estimator c) a dispersion d) a confidence interval e) one should not plan for an error
The number of sampling units taken from each stratum is _________ proportionate to the size of the strata and _________ proportionate to the variance of the measured variable in these strata. a) directly, directly b) inversely, inversely c) directly, inversely d) inversely, directly e) does not depend on size and variability
Explanation / Answer
In an SPSS output for Analysis of Variance for each independent variable F-statistics and Level of Significance of F is computed. Assume the level of significance for a given variable is 0.0000. Which of the following is true:
Answer : this variable has a negligible impact on the dependent variable.
In case of stratified random sampling the stratas should contain units similar in terms of studied characteristic.
Answer : True
The degree of sampling error that is expected and planned for in a study is represented by:
Answer : a confidence interval
The number of sampling units taken from each stratum is _________ proportionate to the size of the strata and _________ proportionate to the variance of the measured variable in these strata.
Answer : directly, inversely
