The purpose of this assignment is for students to show an understanding of Research Methods in Psychology and the terms associate with it. Students must then apply this understanding to specific examples and their own life.
To successfully complete this assignment, students must:
Answer every question in complete sentences!
Include textbook citations within the answer in APA style.
Make sure that there is an APA reference page attached to the assignment.
Make sure to follow all directions in the assignment, including word counts.
Upload the assignment by the due date, including the APA Reference page.
Hint: When using Google docs the formatting gets messed up on the Reference page when the document is uploaded. This means you will lose points for APA style since formatting is important. You might want to save your assignment as a PDF file and then upload it!
For this assignment answer the following questions:
Explain Correlational methods. Make sure you cite the textbook in the answer using APA style. Provide two personal examples of correlations in your own life. Hint: Think of two variables in your personal life that are strongly related to each other. These cannot be examples from the textbook even if they happened in your own life. They must be different! Be very specific about these examples including in the description what happens to one variable when the other increases or decreases. Also make sure to define whether these are positive or negative correlations! (7 pts; Minimum 60 words, include word count )
In Experimental methods the variables are called the independent and dependent variables. Define these variables. Make sure you cite the textbook in the answer using APA style. (2 pts)
On the following page are research examples. You must identify the independent and dependent variable in each example. Remember to use complete sentences! When Identifying the independent and dependent variable you cannot use generic terms like mathematical ability but must explain specifically what was manipulated in each example (independent) and specifically what was measured in each example (dependent). (8 pts; 1 pt. each correct answer)
What is the most important thing that can be shown using the Experimental method that cannot be shown using the Correlational method? (3 pts)
Includes an APA Reference page with appropriate pages cited and uses APA referencing style in the assignment when answering questions. (3 pts)
Grammar/spelling mistakes, word counts, use of complete sentences (2 pts)
A researcher was interested in finding out if exercise was related to mathematical problem-solving ability. The researcher randomly assigned subjects to one of two groups: one group did 50 jumping jacks and the other group did 200. After exercising both groups completed a set of math problems and the researcher measured how many problems each subject got correct.
What is the Independent variable and the Dependent variable in the example above?
A researcher was interested in finding out whether talking to plants was related to plant growth. To test this idea she used 20 plants where all 20 plants had the same amount of food, water and sunlight. She randomly assigned the 20 plants to 1 of 2 groups: she talked to 10 of the plants for 1 minute/day; she talked to the other 10 plants 10 minutes/day. Every day for one month the researcher measured the height of the plants.
What is the Independent variable and the Dependent variable in the example above?
An experimenter wants to study the relationship between type of milk and infant growth in underdeveloped countries. She randomly assigns 300 infants to either a breast-feeding group or an infant formula group. She then weighs the infants every three days for the first four weeks of life.
What is the Independent variable and the Dependent variable in the example above?
A researcher was interested in finding out if type of learning was related to class performance. She randomly assigns 100 General Psychology into 1 of 2 groups: 50 students use computerized instruction exercises; the other 50 spend an equal amount of time reviewing the text and lecture notes. At the end of the semester the researcher compares final exam scores in both groups.
What is the Independent variable and the Dependent variable in the example above?
