Psych 204 final
Term | Definition |
---|---|
Survey Research Design | Use surveys to obtain a description of a group of individuals |
Four Steps to Constructing a Survey | Develop Survey Questions, Assemble Survey questions, Select who will answer the survey, and administer the survey |
Open-ended Questions(step 1) | Introduce a topic and allow participants to respond in their own words |
Restricted Questions (step 1) | Present participants with a limited number of response alternatives. Writing effective restrictive questions that are not confusing or misleading. |
Basics of Assembling questions (step 2) | Demographics questions should appear at the end. Sensitive questions should appear in the middle. Questions of the same topics should be grouped. Format should be simple and uncluttered. Vocabulary and language style should be easy to understand. |
Response Set (Step 2) | The tendency to answer all questions the same way. (example - Authoritarian F Scale) |
Carry Over or Question Order Effect (Step 2) | When earlier questions influence response to later questions |
Socially Desirable Responding (Step 2) | The tendency to respond not as one feels or behaves but in a socially desirable manner |
Context Effect (Step 2) | The influence of the context of the questionnaire on responding |
Representative Sample (Step 3) | This means the sample closely matches the characteristics of population |
Biased Sample (Step 3) | A sample that is no representative of the population |
Random Sampling (Step 3) | This eliminates the possibility that the sample is biased by the preferences of the person selecting the sample |
Simple Random Sampling (Step 3) | This involves using a technique such as random digit dialing |
Stratified Random Sampling (Step 3) | Involves ensuring that the sample represents the population on selected STRATA variables. EX 70% females is needed |
Cluster Sampling (Step 3) | Requires randomly selecting naturally occuring clusters to be surveyed |
Convenience Sample (Step 3) | Can work if there is no reason to believe there is a bias in the sampling technique |
Face to Face survey (Step 4) | face to face |
Non Response Bias (Step 4) | Whether people who return surveys are representative of all who could receive them |
Internet Survey (Step 4) | Should you administer this anonymously |
Literature Reviews | These combine the results of many studies (greater power and value) These permit researchers to address broad questions |
Narrative Review | Can combine different kinds of studies to address these broad theoretical questions. There is a danger with narrative reviews can cherry pick among research findings. |
Meta-Analysis | Statistically combines results from comparable studies that address the same question. Example Cochrane laboratories |
Steps to conducting a Meta-Analysis | Pick a topic, Collect all relevant data, statistically calculate on effect size, and effect size statistics are summed and average |
Pick a Topic (Step 1) | Try to pick something you are knowledgeable in |
Collect all relevant quantitative studies (Step 2) | State exclusion/inclusion criteria for studies explicitly. Do not rely on computer searches |
Statistics (Step 3) | Meta-analysis involves calculating on effect size statistics |
Effect Size Stats are summed and averaged (Step 4) | Is the overall effect size different from zero? are the effect sizes heterogeneous |
Four conclusions from any literature review | 1. Hypothesis is correct 2. The hypothesis is not proven but is currently the best guess 3. No conclusion, not enough evidence or the evidence is flawed 4. The hypothesis is wrong |
Apples and Oranges (3 criticisms) | Combining results from studies that measure different things, manipulate different variables, and test different subjects |
File Drawer (3 criticisms) | The failure to obtain all or a representative sample of the population of studies. (Foreign language studies, unpublished studies, statistically non-significant results) |
Garbage In, Garbage Out (3 criticisms) | Combining poor studies can result in a distorted pictures |
Fail Safe N | Number of studies unpublished that could reverse study |
Code Studies for Quality | systems for assessing quality of studies |
Two types of Articles | The article you planned to write when you designed the study and the article that makes the most sense now that you have seen the results |
Organize Presentation | 1. write in english prose, not jargon 2. Do not plunge readers into the problem(lead them step by step) 3. Use examples to illustrate theoretical points 4. Open with a statement about people |
Method | The method section should provide sufficient detail for replication. Should place reader in the study. Subsections of the method section include participants as well as materials and procedures. Report information on reliability and validity carefully. |
Method 2 | Provide sample questions from survey. Report on ethical issues. |
Results | Don't throw numbers at the readers. Result section should tell a story. Remind us of hypothesis, method and procedures. Tell the answer to the hypothesis in English. Then and only then report statistics. |
Discussion | Tell us what you have learned. Point out implications. Point out limitations. Have a big finish. |
Title and Abstract | Titles should be informative and catchy. The abstract should be a mini version of the paper. |
Tell a good story(Twelve Tips for Authors) | |

Descriptive Statistics | Describe the characteristics of a set of scores |
Mean | Average score |
Median | Middle score |
Mode | Most frequent score |
Measures of central tendency | mean, median, mode |
Standard Deviation | A quantity calculated to indicate the extent of deviation for a group as a whole. |
Inferential Statistics | Allow us to generalize from samples to populations. Separates signal from noise. |
Sir Ronald Fisher | Father of inferential statistics. |
Milk or Tea experiment | milk or tea. decided that if the event occurs less than 5% of the time by chance p < 0.05 |
Probability | The chance that something will occur |
Students T-Test | Puts fishers p < 0.05 into equation |
Anova | For more than two groups |
Pearson's Correlation | tests the relationship between variables. Signal is the strength of the relationship between variables |
Regression | To predict on variable from another variable |
Univariate Statistics | Examine on dependant variable |
Multivariate Statistics | examine multi dependent analysis (factor analysis) |
Qualitative Research | Roots in sociology and anthropology. Focuses on social problems. Seeks to develop a holistic picture of social problems. Informants as basis for reports. Trustworthiness of their data less interested in reliability and validity. |
Confirmability | The extent the report is accurate, unbiased and unconfirmable. |
Dependability | The extent to which the same report would result if the study was replicated |
Credibility | The accuracy of the description of subjects of the report |
Transferability | The extent to which the report can be generalized to other settings and groups |
Grounded Theory | Goes beyond description and interpretation to build theories |
Coding | The heart of grounded theory |
Open Coding | The researcher categorizes the phenomena being studied |
Axial Coding | Finding links between categories from open coding |
Selective Coding | Identifying a core category and relating other categories to this core |
Process and Transactional System | Try to build the theory |
Participatory Action Research | Knowledge is rooted in social relationships and produced collaboratively through action |
Mixed Methods | Quanitative and qualitative |
Training as a researcher | The first step is to obtain a bachelors honour degree. Then graduate school. Then get a job. |
