|
Definition
| Use numbers as the main way of demonstrating results;objective;uses numbers and statistics to address the research question;uses subjects rather than participants |

|
Definition
| Narrative; less scientific; trying to undertand some phenomenon from the perspective of the participant, not subject; less scientific; methods are interviews, observations, document analysis. |

Definition
| Narrative descriptions or observations |

|
Definition
| On control of variables in the study. |
|
|
Term
| Mixed method design involves which two research designs? |
|
Definition
| Quantitative and qualitative |
|
|
Term
Specific mixed method designs: Explanatory design Explain this design |
|
Definition
| It begins with quantitative research, and the qualitative research, and then explains the findings. |
|
|
Term
Specific mixed method designs: Exploratory design Explain this method |
|
Definition
| It begins with qualitative research, then quantitative research, and then presents the findings. |
|
|
Term
Which mixed method research design is being used in this example? The researcher conducts a survey, then explores the participants' feelings, inquires about wanting to know more, then designs an interview. |
|
Definition
|
|
Term
Which mixed method research design is being used in this example? The researcher doesn't know much about the participants, so he goes into the field to observe, then creates a survey for the participants to complete. |

|
Term
| What are some methods of data collection and analysis in quantitative research design? |
|
Definition
| quasi-experimental, experimental, true experimental, single subject design, non-experimental, descriptive, survey, correlational, ex post facto, and comparative. |
|
|
Term
| What are the benefits of using a mixed methods research design? |
|
Definition
It can increase the reliability and applicability of research conslusions because it provides more and different types of information related to the same research question. |
|
|
Term
Methods of data collection and analysis Which research design is being used in this example? A researcher identifies high-poverty schools in the state that have either high or low student achievement. The researcherdescribes the alignment or match between each school's curriculum and state standards and compares the high versus the low achieving schools to determine whether the degree of alignment is different. |
|
Definition
| Comparative descriptive research design |
|
|
Term
Methods of data collection and analysis quantitative research What method is being used in this example? In school district X, a researcher collects data on beginning teacher's scores on the state licensing test (variable 1) and data on the achievement gains of each teacher's students (variable 2). The researcher then uses correlational statistics to measure the association betweem the two variables. |
|
Definition
| Correlational research design (bivariate correlation) |
|
|
Term
Methods of data collection and analysis in quantitative research What method is being used in this example? In school district X, a researcher collects data on beginnin teacher's scores on the state licensing test (variable 1), the number of college courses that each teacher completed in math (variable 2), the amount of time that each teacher spent in school-based field experiences prior to certification (variable 3), and the achievement gains in math by each teacher's students (dependent variable). The researcher uses multiple regression statistics to measure the association between the three teacher variables and student achievement gains and to stimate student achievement gains based on the contribution of each of the teacher variables to that association. |
|
Definition
| Correlational design: multivariate correlation (also known as multiple regression) |
|
|
Term
| What is descriptive research? |
|
Definition
| Research that aims at describing what, how, or why something is happening. It uses numbers to characterize individuals or groups. |
|
|
Term
Describe experimental (true) research design |
|
Definition
| A research design in which (1) an independent variable is directly manipulated to measure its effect on a dependent variable, and (2) participants are randomly assigned to different groups that recieve different amounts of the independent variable. |
|
|
Term
| Describe ex post facto research |
|
Definition
| Descriptive research that examines the influence of a preexisting independent variable or treatment. |
|
|
Term
| Describe quasi-experimental research design |
|
Definition
| A research design in which (1) the independent variable is manipulated to measure its effects on a dependent variable, and (2) participants are not randomly assigned to comparison groups. |
|
|
Term
| Define multiple regression analysis |
|
Definition
| A statistical technique that determines the linear association between a set of predictor variables and a dependent variable and identifies the combination of predictor variables that best estimates the depedent variable (also referred to as the criterion variable) |
|
|
Term
| What is a correlation coefficient? |
|
Definition
| A number that indicates the strength and direction of the statistical association between two or more variables. Correlation coefficients vary between -1.00 and +1.00. The higher the numerical value, the stronger the association. A correlation of 0.00 indicates the absence of an association. A positive sign means that as one variable increases, so does the other. A negative sign means that as one variable increases, the other variable decreases. |
|
|
Term
|
Definition
| A statistical technique used to make inferences about a population of study participants based on a sample of these participants or to test for statistically significant differences between different groups of observations. |
|
|
Term
|
Definition
| Analysis of variance. It is an inferential statistical procedure for determining the level of probability of rejecting the null hypothesis with two more means. |
|
|
Term
| Name sampling techniques for qualitative design |
|
Definition
| Comprehensive sampling (every participant is included), maximum variation (represent differences), network sampling (use participants to lead you to the next participant), case type (based on characteristics. |
|
|
Term

|
Definition
| observation, in-depth interviews, document collection. |
