Define the expected value of sample means

the mean of the distribution is the standard deviation of the distribution
equal to the mean of the is equal to the population
population of scores μ mean
Retest missed terms Turn these into questions
, the median of the distribution is the mode of the distribution is equal
equal to the population mean to the mean of the sample scores

Is there a formula to find the median for scores that are not in
intervals?

find the sample mean difference
find the z score for x=14, look it up in the unit normal table
no
1.to simplify the organization and presentation of data for descriptive statistics.
2.demonstrate the data and provide a visual way of manipulating it to gain
statistical insight.

What is ANOVA?
when is it used?
what test statistic is used?
Give this one a try later!
Analysis of variance, used to measure the differences between two or more
treatments of populations.
anova is used when there are 2 or MORE treatments, giving flexibility to have
more than one treatment and be able to infer the results.
f-ratio
a measure of effect size that assesses the difference between two means in terms
of standard deviation, not standard error
use cohen's d when doing z-score test
use cohen's estimated d when doing the t-test
when information about the population (standard deviation, variance) is not known.
use the t statistic for an independent-measures design or a repeated-measures
design
you use the t statistic to test hypothesis about unknown populations.
, populations have larger variability than samples. populations include extreme
scores, and this correction brings it closer to the what the estimated population
variability would be.
also, n-1 means that if you took the average of each and ever possible sample
variance, the average sample would produce an accurate estimation of the
population variance.
