task 14

What are two types of Inferential Statistic?

• Hypothesis testing and Linear analysis

• Hypothesis testing and Variance analysis

• Hypothesis testing and Regression analysis

• Hypothesis testing and Mean analysis

A statistical hypothesis test used in the analysis of a contingency table when the sample size is large?

• Non parametric procedures

• Nominal

• Chi- square test

• T-test

A numerical value which describes the characteristic of an entire population?

• Statistical

• Parameter

• Numerical

• Hypothesis

Inferential statistic consisting of generalizing from sample to population and making prediction while, Descriptive statistic is the process of using and analyzing the statistic?

• The first statement is true and the last statement is false

• The first statement is false and the last statement is false

• The first statement is true and the last statement is true

• The first statement is false and the last statement is true

In hypothesis testing, when can we reject the null data?

• If the z statistic < z critical value

• if the t statistic > t critical value

• If the f statistic < f critical value

• if the t distribution is less than 30

This demonstrates whether changes in predictor variables change in an outcome variable?

• Regression test

• Comparative test

• Correlation test

• Comparison test

What are the numerical techniques for making conclusion about a population based on information obtained from random sample drawn from the population?

• Descriptive statistic

• Inferential statistic

• Statistic

• Sampling

What is a testable prediction about real-world phenomenon?

• Hypothesis

• Conclusion

• Experimental

• Control

It assume only a finite or countable number of values ( with one to one correspondence with the set of whole number)

• Discrete

• Continous

• Qualitative

• Quantitative

This technique uses randomization to make sure that every element of the population get an equal chance to be part of the selected sample?

• probabilty sampling

• Non -probabilty sampling

• convenience

• referral sampling
