  1. CorRELATIONal Research Sandy Aguirre

  2. to explain and define Correlational Research • to apply this method in the students’ research paper • to appreciate the significance of the Correlational Research Method in further understanding the relationship between two variables Objectives:

  3. YOU are at the CURIOSITY stage! YOU have a lot of questions in mind…YOU always ask WHY? HOW? WHAT?

  4. RESEARCH is one way. There are several ways of collecting and understanding- information and finding answers to your questions –

  5. • Research is an art of scientific investigation. • It is regarded as a systematic efforts to gain new knowledge. •The dictionary meaning of research is “a careful investigation or enquiry especially through search for new facts in any branch of knowledge”. What is Research?

  6. What is a Correlational Research?

  7. It is a research design under the Non-experimental Quantitative Research. What is a research design? It’s the methodology and procedure used to conduct a research. So what is a Correlational Research?

  8. • It refers to the organized investigation or statistical study of relationships among two or more variables, without necessarily determining cause and effect. For example, to test the hypothesis “ Listening to music lowers blood pressure levels” Correlational Research

  9. • establishes only an association between variables rather than a causal relationship; • needs hundredsor eventhousandsof subjects for accurate estimation of trivial or small effects. Non-causal: does NOT tell us that Variable A caused Variable B, but rather that they are somehow related by a hidden variable.

  10. • Positive Correlation: when two variables go in the SAME direction. •Negative Correlation: A relationship between two variables in which one variable increases as the other decreases, and vice versa.   Direction of a Correlation

  11. The less bowling time The less violence at home Positive Correlation The more time in the mall The less money I have in my checking account Negative Correlation

  12. A correlation analysis which tries to measure the strength of a relationship between two variables through a number. The correlation coefficient is a number between +1 and -1: the closer to either number, the stronger the relationship. Correlation Coefficient

  13. Correlation Between Grade Point Average and Absences by Ignacio SuarezPrepared for Professor ErlynBaackITESM, Campus Queretaro A sample correlational research

  14. Students felt that the relation is not that strong because, "You may go to all your classes, but not pay attention," or "It depends whether you study or not," so consequently, the grades depended on other factors. Some more students thought that absences do affect grades because of these reasons: "If you have an absence, you lose the sequence of things." "You miss the interesting themes." "The teacher explains better than any classmate." or, "The teacher might have a different way of thinking." What the respondents think:

  15. To prove the existence of a relation, or dependency, between absences and grades a regression analysis was conducted. A regression analysis shows the dependency of a variable (grades in this case) to an independent factor (absences). The analysis resulted in an R square of .23 which means that 23% of a grade can be explained through absences. The correlation between grades and absences is: as the absences increase, there is more variation in the grades that the students get. Result of the research: Correlation Coefficient: The correlation analysis proved a mild, but significant, correlation of -.44.

  16. some actually show a positive correlation (Maestria 0.17 and LEM 0.006), meaning that the fewer classes a student goes to, the better grades he/she gets.

  17. Plagiarism involves: • Copying someone else’s ideas or words and not citing them • Getting credits from another student’s work • Cutting and pasting text from the Internet and passing it off as your own • Purchasing someone else’s work and describing it as your own Plagiarism – Please Don’t Do IT!
