Exam 8: Hypothesis Testing and Statistical Significance

A hypothesis includes information about the ___________________ of interest and the relationship between them.

Jim hypothesizes that the alternative service delivery model will be more effective than the traditional service delivery model. This is an example of a ___________________.

The point at which the researcher determines what will qualify as significant is known as the ___________________.

Explain how inferential statistics are used to make generalizations from the sample to the population.

The steps to confirm the hypothesis are called hypothesis testing.

A(n) _____________________ variable is one that is not part of the hypothesized relationship but may have an impact on the dependent variable?

When the sampling error is higher, the sample data is less representative of the population.

Explain the logic behind hypothesis testing. Why is this an important part of the research process?

Choose one of the cases of Jim, Mary or Emily and write a direction, non-directional and null hypothesis for the case of your choice.

A(n) ______________________ can aid in developing the hypothesis by informing you about which variables have been used in other research and how those variables were measured.

Emily posits that, "people who attend the diversity training will have a higher cultural competency than people who do not attend the training." This is an example of a ____________________.

A researcher is interested in the difference in salaries between men and women. However, she is concerned that the sector in which people work will impact the analysis. So, she accounts for this variable when she performs the analysis. What type of variable is work sector in this study?

The independent variable is also known as a control variable.

If a researcher obtains a p-value of .08, that result is typically considered ___________________ and the researcher should ____________ the research hypothesis.

A hypothesis which states that there is a relationship between two variables but does not specify direction of the relationship is known as a(n) ____________________.

A researcher is interested in examining the impact of parenting style on childhood development. In this example what is the independent variable?

A _____________________ is used to determine if the null hypothesis should be rejected.

When the null hypothesis should be rejected but it is not, this is known as a __________________.

Rejecting the null hypothesis when you should not is known as a __________________.

The level of significance is always .05.
