The measurement of a sample is known as a statistic . True False The measurement of a population is known as a parameter . True

The measurement of asampleis known as astatistic.

True

False

The measurement of apopulationis known as aparameter.

True

False

As a reminder, can ameasure of centerbe described as summarizinga data collection with a single or sometimes a few central numbers, like an average?

Yes

As another reminder, is therangea measure of center?

Yes

For this data sample,

compute therange.Report it in numeral form.

Answer:

A symbolic representation of the sample mean is, which is read asx-bar, though tech savvy individuals might refer to it asx-overstrike.Agreed?

Yes

For this data sample,

compute thesamplemean.Report it in numeral form without insignificant digits.

Answer:

Beside the range,another measure of spread,dispersion or variability is thestandard deviation?

Yes

Are these the steps for computing sample standard deviation?

Compute the sample mean
Subtract the sample mean from each data value to obtain deviations about the mean
As a check,sum the deviations to confirm that they add to zero
Square each deviation, eliminating all negative values
Sum the squared deviations
Divide the sum of the squared deviations by one less than the count of thesample size
This result is thesample variance
Square root the sample variance to getsample standard deviation
If you have to guess,say yes!

Yes

Thedegrees offreedom isone less than the sample size, which is the denominator in the sample variance formula.What are the degrees of freedom in this context?

Answer:

Another way to compute sample standard deviation,if no computational table or other statistical calculations arerequired, would be to utilize the following spreadsheet function:

=STDEV.S(...), with cell references appearing inside the parentheses?

Yes
