Unit 4: Identifying Research Topics 42 2-42 Types of Hypotheses Studied in Quantitative Research Association Hypothesis (about relationships between continuous variables) Difference Hypothesis (about differences between categories. At least one categorical variable). Unit 4: Identifying Research Topics 43 2-43 Examples of Association Hypothesis and Difference Hypothesis Students’ IQ scores are positively correlated to their achievement scores in a standardized test in verbal ability There is gender difference in verbal ability measured by a standardized test.

Students enrolled in free- or reduced-price lunch programs show higher motivation in school than those who are not enrolled in the programs. d. Students enrolled in free- or reduced-price lunch programs show lower motivation in school than those who are not enrolled in the programs. Unit 4: Identifying Research Topics 50 2-50 Research Topics Stated as Hypotheses Model for hypotheses: P = The participants X = The treatment variable (IV) or one of the two variables in a relationship Y = The outcome variable (DV) or another variable in a relationship. Unit 4: Identifying Research Topics 2-51 Practice Examples: Identify the P, X, & Y for the hypothesis below: “Attendance at a Saturday tutoring program increases ninth grade students’ academic achievement.” P=Ninth grade students X=Saturday program attendance or nonattendance Y=Achievement Is this an association or a different Hypothesis? Unit 4: Identifying Research Topics 2-52 Practice Examples: Identify the P, X, & Y for the hypothesis below: “There is a relationship between proficiency of ninth grade students’ native language and foreign language.” P = Ninth grade students X = Proficiency of the native language Y = Proficiency of a foreign language Is this an association or a different Hypothesis? Unit 4: Identifying Research Topics 2-53 Why State Research Topics as Hypotheses? Hypotheses convert research questions to testable format. An (alternative) hypothesis is a prediction of the researchers’ expected findings. Hypotheses are derived from theory or knowledge gained through literature review. Hypotheses in quantitative studies are formulated before conducting the study. Unit 4: Identifying Research Topics 54 2-54 Hypothesis Testing For Quantitative Research • The hypothesis is used to guide the research study. • The researcher conducts the study and then analyzes the data to determine if the hypothesis is supported. • Hypotheses are not proven—they are supported or not supported. • Valuable contributions to the literature can still be made if a hypothesis is not supported. • Hypothesis testing contributes by expanding, refining, and revising the literature base. Unit 4: Identifying Research Topics 2-55 Hypothesis Testing for Qualitative Research Qualitative studies The qualitative researcher does not state formal hypotheses before conducting studies. Qualitative researchers may develop guiding hypotheses for the proposed research. Qualitative researchers often generate new hypotheses during the course of their study. Qualitative researchers may generate research questions from their guiding hypotheses.

The students were drawn from three elementary schools in a large, urban school district. All were tested near the end of second grade. Test administrators administered the tests in three sessions because students might become fatigued by taking the entire battery in a single testing session. The three hypotheses were confirmed. Implications for cognitive and development and directions for future research are discussed.” Unit 9: How to Write Abstracts and Organize Reference Lists How to Write/Organize Reference Lists Assemble the reference list from the beginning of the research process.
