can express how

the 2 distributions DIFFER

• measures of variation

• measures of central tendency

• range

• variance

largest - smallest measurement

• measures of variation

• standard deviation

• range

• variance

larger range = _____ variation

• more

• less

Range is NOT THE BEST MEASURE of a data set’s VARIATION

• true

• false

a measure of the SPREAD of population data.

• population variance

• standard deviation

• range

• sample variance

average of the distances from each data point in a particular population to the mean squared.

• population variance

• standard deviation

• range

• sample variance

average of the squared deviations (differences) of the individual population measurements from the population mean μ

• population variance

• standard deviation

• range

• sample variance

positive square root of the population variance (denoted by SIGMA)

• population variance

• population standard deviation

• range

• sample variance

MORE SPREAD OUT the population measurements >>>

the ___ are the Population Variance & Population Standard Deviation

• smaller

• larger

more often used to make practical interpretations about variation of data set values

• population variance

• population standard deviation

• range

• sample variance
