an interval of plausible values for a parameter based on sample data (most common is 95%)
3
New cards
confidence level C
the overall success rate of method used to calculate confidence interval - “we are C% confident that interval _ captures % of parameter.”
4
New cards
margin of error
how far (at most) estimate is expected to vary from point estimator in C% confidence interval
5
New cards
decreasing margin of error…
confidence level decreases; sample size increases
6
New cards
critical value
a multiplier that makes interval wide enough to have the stated capture rate
7
New cards
3 conditions for validity of confidence interval p…
1. random sample
2. large counts: np^ ≥ 100 & n(1-p^) ≥ 100
1. 10%: n < 0.10N
8
New cards
standard error
estimate of the standard deviation of a statistic via data
9
New cards
confidence interval
point estimate ± margin of error OR statistic ± critical standard error
10
New cards
