This activity contains 18 questions.

	The research design describes   The methods that are used to develop the research topic. How the researcher designed the entire study. The statistical procedures to be used in the study. The procedures that are used to collect the data

	Which of the following is NOT a non-experimental research design?   Quasi-experimental Causal-comparative Descriptive Correlational

	A descriptive design can be characterized as a study that   Predicts subsequent events from something happening at the moment Provides information about existing phenomena. Describes the relationship between two variables. Examines the effect of an independent variable on a dependent variable

	Results of a descriptive study on the sharing behavior of first-grade students showed that children with siblings displayed sharing behavior more often than children who did not have brothers or sisters. The researcher concluded that children were more likely to learn to share if there were other children in the family. Which criterion for descriptive studies has been violated in this example?   Descriptive studies describe behaviors or events. The researcher should provide detailed descriptions of the subjects used in the study. Descriptive studies do not assume causal relationships between variables. The results from descriptive studies should not be distorted when presented in graphics.

	Which of the following statement is NOT TRUE of relationship studies?   Relationship studies enable us to establish a causal relationship between two variables. In relationship studies, groups of students can be compared. Relationship studies enable us to make predictions. Relationship studies investigate the relationship between two variables.

	A researcher investigated the relationship between class attendance and grades among sophomores at a state university. What type of research did she use?   Ex post facto Predictive Correlational Comparative

	Which of the following statements describes a prediction study?   One set of data is collected for a group of participants. A correlation coefficient shows the relationship between two variables. The criterion variable is used to make predictions about future performance. The predictor variable is used to predict the criterion variable

	Predictions in education will be more accurate if   A single predictor variable is used. There is a long time span between the predictor and criterion measures. Highly reliable predictor and criterion measures are used. ANCOVA is used to statistically analyze the data.

	A correlational study should be judged acceptable if it meets all of the following criteria EXCEPT   The researcher explained what brought about a high correlation between two variables. Highly reliable measures were used by the researcher. The researcher selected an appropriate sample for the study. The study tested the accuracy of the predicted relationship.

	Ex post facto research is characterized by which of the following?   The researcher controls the independent variable and studies its effects on the dependent variable. The independent variable is not know to the researcher. Only subjects who have had similar experiences (independent variables) are included in the study. Subjects are only measured on the dependent variable.

	In a study on the reading achievement of two groups of second-grade students, it was found that children who came from homes where books were valued and where parents started reading to them from an early age were more likely to have higher reading scores than children who came from home where reading was not considered important. This is an example of   A longitudinal study Ex post facto research Experimental research A cross-sectional study

	Which of the following is NOT a reason for the popularity of surveys?   Response rates are typically high. They are efficient methods for collecting data. The results are usually generalizable. They are versatile.

	A researcher studied the voting plans of a sample of voters during the gubernatorial elections. At the beginning of the election campaign, half the sample supported the Republican candidate and the other half supported the Democratic candidate. However, several months later, and prior to the election date, he found that some of the voters in his sample had changed their opinions. At the end of the study, 20% of his sample supported the Republican candidate and 80% supported the Democratic candidate. This is an example of a(n)   Comparative study. Longitudinal study. Cross-sectional study. Ex post facto study.

	Which of the following would you recommend to a student designing a survey to examine the opinions of teachers toward a new district grading policy?   Develop a clear set of directions. Define the purpose and objectives of the survey in specific terms. Pilot test the survey. Develop a letter of transmittal. All of the above.

	Which of the following represents the BEST situation for using an Internet-based survey?   Examining the opinions of third-grade students. Collecting data on teacher's use of alcohol. Gathering information on the effectiveness of the companion Website for a textbook from professors who use the site. Collecting teacher's opinions about the effectiveness of their principal.

	A researcher has conducted a study examining the extent to which graduate students' performance in an introductory research class can be predicted from their GRE scores and their undergraduate GPA. Her sample consists of 10 students from her class who volunteered for the study. Which of the following is disconcerting about this study?   The causal relationships. The operationalization of the variables. The sample size. The confidentiality of the students' scores.

	A researcher conducted a survey of all secondary teachers in Orleans Parish. Which of the following would be of concern to you?   There were a few minor formatting problems due to his switching printers for the final copy. His response rate was 35%. He did not pilot the study. All of the above.

	Which of the following is NOT a criterion for evaluating causal-comparative research?   Researchers should infer cause-and-effect relationships. Extraneous variables should be controlled by the researcher. Statistical procedures should be used to control for possible differences between subject groups. The independent variable should already have taken place.
