3. Which of the following is NOT a characteristic of quantitative computer programs?
a. they are available in both mainframe and micro versions b. they allow you to input the data for your statistical analysis c. they provide all of the statistical tests you would probably need d. they are about as difficult to learn as a word processing program |
c

4. When inputting data into a computer program for data analysis, “values” are:
a. the numbers associated with variables you are trying to measure b. the response options to variables you are trying to measure c. the quality of information for variables you are trying to measure d. the identifying number for variables you are trying to measure |
b

5. A quantitative researcher uses a data analysis computer program to explore the database. The intent of this exploration is typically to: (check all that apply)
a. clean up the database b. search for missing information c. form results to descriptive questions d. see if the score represent a normal distribution |

6. An individual who has completed your research survey instrument has not responded to question 10 and has chosen to leave it blank. For purposes of quantitative data analysis, how would you respond to this issue?
a. send the instrument back and ask the person to fill out the question b. delete the individuals survey completely from the database c. assign a value for missing information such as a –999 d. recontact the person and ask them why they did not respond |

7. You are looking at a plot of scores for 500 students on a self-esteem scale. This plot, shown on a graph, indicates a steep curve to the right on the histogram. What name might you give to this distribution of scores?
a. a right curve distribution b. a positive kurtosis distribution c. a positive normal distribution d. a negative skewed distribution |
d

8. You are reading a research report summarizing the findings for a study of first-year teacher anxiety in the classroom. You read the following results:
“The average score for teachers on all items on the anxiety instrument was 65.76 with a standard deviation of 5.6. The scores varied from a low of 45 to a high of 75 on the instrument.” What type of research question would likely result in this type of statement? a. a comparison question about teacher scores b. a relationship question correlating years of experience and anxiety c. a descriptive question measuring the anxiety of teachers d. a range of scores questions assessing the variability of scores |
c

9. Which of the following steps is NOT a procedure in quantitative data analysis?
a. examining the trends in the data b. determining effect sizes c. scoring the data d. analyzing the differences among themes in the data |
d
|
|
|
10. Which of the following is NOT a factor to consider in selecting an appropriate statistical test for a quantitative study?
a. how many independent variables there are b. what the scale of measurement is on the variable c. whether the independent variable is compared or related d. whether the independent variable relates to the question |
d
|
|
|
11. The two areas at the end of a normal curve that indicate an extremely low probability of values if the null hypothesis is false is called:
a. a two-tailed test b. the area of the critical region c. the area of the true null d. the significance level or alpha |
b
|
|
|
12. Which of the following is NOT a possible outcome of hypothesis testing?
a. the probability of alpha b. the probability of beta c. the power of the test d. the beta weight of the null |
d
|
|
|
13. If a researcher sets the alpha at .05 and obtains a p-value of .06, this means that a null hypothesis would:
a. fail to be rejected b. be slightly higher than alpha c. be very close to the alpha level d. be accepted as different |
a

14. Examine the following statement found in the conclusion to a quantitative research study:
“One reason why the results were insignificant may be due to the small size of the sample and the use of a convenience, rather than a random, probability sample.” This statement indicates that the researcher is: (select all that apply) a. advancing a delimitation of the study b. providing an explanation for the results c. sharing why evidence did not support predictions d. suggesting future research to strength the study |
bc

15. In the parent involvement study (Deslandes & Bertrand, 2005), the researchers state a finding in paragraph 27:
“Parents’ perceptions of students’ invitations in the social domain was the most powerful predictor; it accounted for an additional 28% of the variance (beta-.35, p<.001).” From looking at the p-value you would conclude: a. that the results were statistically significant b. that the probability alpha level was set too low c. that the authors should have set an exact p-value d. that the partial results indicated a significant p-value of .001 |
a
