Standard Deviation
A statistical measure that quantifies the amount of variation or dispersion of a set of data values.
Mean Height
The average height of a group of individuals, calculated by summing their heights and dividing by the number of individuals.
Confidence Interval
A spectrum of values obtained from statistics of a sample, which is likely to encompass the actual population parameter at a specific probability level.
- Absorb the concept of a confidence interval and its function in the estimation of parameters within a population.
- Recognize the impact that different confidence levels (such as 90%, 95%, 99%) have on the span of confidence intervals.
- Understand how sample size affects the confidence interval.
