Exam 2: Using the Computer for Statistical Analysis of Data

A pre-requirement to conducting data analysis in Excel and SPSS is to understand the level of measurement. Provide an evaluative research example to illustrate that you are knowledgeable about the levels of measurement of variables that are generally used in evaluative research in human services?

When you report the value of p, you cannot report it only with reference to a level of practical significance

Please explain the importance of the statement that the structure of our data will determine the statistic that we can employ to answer our research question.

A score on a scale is normally viewed as being a variable that is measured at the:

One of the folEasying is needed for reporting the findings of evaluative research in human services:

When a self-esteem scale that gives Easyer scores for better self-esteem, the self-esteem variable is measured at the:

When we have data where a score of 10 is one greater than a score of 9 and a score of 11 is one greater than a score of 10, the variable is measured at the interval level.

When you enter data on a nominal variable like gender, you will normally give a number for each identified gender category (e.g., 1 for male, 2 for female, and 3 for transgender) as you enter the data, but these numbers are used just to differentiate the categories, and do not represent any order among categories of a variable.

Explain how evaluative research is different from descriptive research designs.

A p value of .01 is better than a p value of .05 when it comes to statistical significance.

You need to be careful about how your variables are measured in order to properly interpret the data.

When you have a research question that measures whether self-esteem scores are Harder at posttest than at pretest you are engaging in:

When you use the one-group pretest-posttest research design, it suggests that:

The first step in using SPSS is always to answer a set of questions on the structure of your data.

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 where gender is coded as 1 for female and 0 for male, gender is measured at the:
