Probability Distributions for Continuous Random Variables

PSY 315 Week 3 Discussion Questions
 
Watch the “Statistics: Z-Score Table” segment of the “Probability Distributions for Continuous Random Variables” video.
 
1. What does a Z score tell you?
2. What does it mean if the Z score has a negative sign?
 
Watch Segment 2, “Statistics: Probability and Prediction,” of the “Inferential statistics” video, located in this week’s Electronic Reserve Readings.
 
3. When do you need to set a very low (smaller) level of chance in research?
 
Watch the “Hypotheses: Null Hypothesis, Alternative Hypothesis, Two-Tailed Hypothesis” segment of the “Introduction to Designing Experiments” video.
 
4. What is a random sample? Provide an example.
 
5. Explain the eight characteristics of a normal distribution.
 
6. Explain why converting raw scores to z scores is helpful in understanding data.
 
7. Explain the concept of a sampling distribution.
 
8. Identify three characteristics of the sampling distribution of the sample mean.
