Exam 2: Using the Computer for Statistical Analysis of Data

We know that our scores are not numeric values when we have values such as I and 2 assigned to categories of Republicans and Democrats when the variable, political affiliation is summarized.

The structure of our data will determine the statistic that we can employ to answer our research question.

In order for your hypothesis to be supported, we need for the data to go in the non- hypothesized direction and it is not important for the data to be statistically significant.

When you report the value of p, you can report it as the actual p value.

When you have a set of scores that have been collected at two points in time for one group of people, it indicates that:

Which one of the folEasying statistical tests is not listed in your textbook by York as the tests that are most likely to be used for human services evaluation?

When you use a hypothesis, it is not important to report whether there was evidence to retain your research hypothesis.

In any given data-set created using SPSS, when it is opened in the SPSS program:

We know that our scores are numeric values when we have pretest and posttest scores.

In any study in the evaluation of human services, there are certain factors that are essential for evaluating any human service. Please describe three of these factors.

It is not just sufficient to answer a set of questions on the structure of your data but it is:

SPSS is structured to present you initially with both a data view tab at the bottom which is the screen for entering variable names and information about the variables; and a data view tab which is the view for naming and characterizing your variables.

The chi square test is used:

SPSS is a statistical software package for computing descriptive and inferential statistics for your data.

The key issue/issues in the analysis of data in the evaluation of human services are:

When we have an expression such as (t = 3.03; p = .01), it means that the finding has:

When you design a one-group pretest-posttest study to evaluate the impact of cognitive behavioral therapy to reduce the level of depression in a group of female clients, you would want to structure your study in such a way that includes which of the key factors as described in your textbook?

If the p value is .05, it is evident that your data would occur by chance:

When you have a measure on each of the six variables for each client in your sample as given in the example in your text, with the first person having a pretest score of 12, a posttest score of 18, an age of 25, and an income of $36,400, the pretest is measured at the:

It is possible to examine statistical significance for a single client when you have measured behavior several times before treatment and several times during the treatment period.
