What does this symbol refer to? sigma • What is it called? • What does it mean? • Is it referring to a sample or population? population The mean (population) 2. What does this symbol refer to? mu • What is it called? • What does it mean? • Is it referring to a sample or population? population The mean (sample) 3. What does this symbol refer to? x-bar • What is it called? • What does it mean? • Is it referring to a sample or population? sample The standard deviation (sample) 4. What does this symbol refer to? s • What is it called? • What does it mean? • Is it referring to a sample or population? sample 5. What does this symbol refer to? Each individual score**Review Notations**population sample 6. What does this refer to? Variance • What are they called? • What do they refer to? • How are they different S squared Sigma squared 7. What does this refer to? sample population Deviation scores • What are they called? • How are they different population sample 8. What do these two refer to? Sum of squares • What are they called? • How are they different 9. What does this refer to? Degrees of freedom • What is it called? • Use it for sample data or population? sample**Review notations**Standard Deviation 10. What does this refer to? • What are they called? • What do they refer to? • How are they different population sample Variance 11. What does this refer to? • What are they called? • What do they refer to? • How are they different population sample 12. What does this refer to? z score • What is this called? • What does it mean? Distance from the mean (counting by standard deviations)**z scores**z score: A score that indicates how many standard deviations an observation is above or below the mean of the distribution z score = raw score - mean standard deviation How are standard deviations (or z scores) related to probability (also known as area under the curve or proportion of curve or percent of curve)**Mean = 100**Standard deviation = 5 If we go up one standard deviation z score = +1.0 and raw score = 105 z = +1 z = -1 68% If we go down one standard deviation z score = -1.0 and raw score = 95 85 90 95 100 105 110 115 If we go up two standard deviations z score = +2.0 and raw score = 110 z = +2 z = -2 95% If we go down two standard deviations z score = -2.0 and raw score = 90 85 90 95 100 105 110 115 If we go up three standard deviations z score = +3.0 and raw score = 115 99.7% z = +3 z = -3 If we go down three standard deviations z score = -3.0 and raw score = 85 85 90 95 100 105 110 115 z score: A score that indicates how many standard deviations an observation is above or below the mean of the distribution z score = raw score - mean standard deviation**Thank you!**See you next time!!
