Lecture 3: Statistics Flashcards
1
Q
big sample size
A
more reflective of the actual population; low standard error.
2
Q
small sample size
A
more likely to calculate a sample mean that is different from the population mean; high standard error.
3
Q
standard error
A
indication of how close the sample mean (x/) is to the population mean (m).
4
Q
standard deviation
A
how close the majority of the population sits to the mean. narrow = little variation ; wide= more variation
5
Q
statistically significant (,,)
A
the difference is not just due to chance.
