Psychology stats

Answer all 7 questions Use original examples for every question. Do not use or closely mirror examples discussed in class, lectures, discussions, or course materials. Clearly label all required components (e.g., research question, hypothesis, independent variable, dependent variable). Organize responses so each answer is easy to follow. more student-facing. Late submissions are not accepted without prior approval. The assignment is due Thursday, February 26 at 9:30 PM Statistical Notation & Extra Credit When appropriate, you may use standard statistical symbols (e.g., x, , , s) or clearly include the statistical concept in words (e.g., sample mean, population standard deviation). Correct and appropriate use of statistical notation or terminology may earn extra credit. Extra credit is awarded for accuracy and correct application, not for frequency or volume. Students will not be penalized if symbols cannot be inserted, provided the statistical meaning is clearly stated in words. Extra credit may be awarded for work that goes beyond basic expectations and demonstrates exceptional understanding, clarity, and application of course concepts overall. assignment Questions Question 1: Research Questions OR Hypotheses (15 Points) Provide one original example of a research question OR one corresponding research hypothesis. Clearly identify the independent variable and the dependent variable in your example. Your example must not be an example used in class. Question 2: Independent and Dependent Variables (15 Points) Create an original research example by clearly identifying one independent variable and one dependent variable. In complete sentences, explain how changes in the independent variable are expected to influence the dependent variable. Your example must not be one discussed in class. Briefly explain how the independent variable is expected to influence the dependent variable. Your example must be different from those presented in class. Question 3: Scales of Measurement and Measures of Central Tendency (15 Points) Provide one original example of a variable and identify its scale of measurement (nominal, ordinal, interval, or ratio). Identify the most appropriate measure of central tendency (mean, median, or mode) for your example and briefly explain why. Do not use an example presented in class. Question 4: Measures of Variability (15 Points) Using one original example, explain two measures of variability (e.g., range, variance, or standard deviation). Describe what each measure indicates about the data in your example. Your example must be different from those presented in class. Question 5: Probability and Types of Distributions (20 Points) Using one original example, answer the following: a. Probability: Explain probability in your own words and provide a clear example showing how probability would be calculated or interpreted in a research context. b. Types of Distributions: Using the same example, identify one type of distribution (e.g., normal, positively skewed, negatively skewed, or uniform). Describe the shape of the distribution. Explain what the distribution tells us about the data. Your example must be different from those presented in class. Question 6: Research Video and Data Collection (10 Points) During lecture, students viewed research videos demonstrating psychological data collection methods. Select one research video shown during class and provide a brief description of the video. In your response, summarize the main points demonstrated in the video. Identify the general research topic presented in the video. Describe how the data were collected, including: Participants Provide a description of the data collection procedures used in the research. Question 7: Lecture-Specific Concept (10 Points) Identify one concept covered in class lecture that is not addressed in any other question on this exam. Your response must include: The specific topic discussed A clear explanation of the concept in your own words An original example that demonstrates understanding Your answer should demonstrate accurate understanding of the lecture content and thoughtful application of the concept. Do not repeat information already used in your responses to Questions 1 through 6. Repeated or recycled material will not receive credit.
