On paper:

• mean, median mode range
• standard deviation (sample and population)
• frequency distribution
• histogram and other graphs (time series)
• finding sample size (given formulas)
• percentile
• relative position (z score/standard score)

On computer

• create new values (like convert grams to pounds)
• max, min, range
• mean, median mode
• Standard deviation (sample and population)
• percentile
• relative position

Ideas to know:

• sample vs population
• types of sampling (Random, Systematic, Stratified, Cluster)
• what standard deviation means
• what relative position means
