Statistics
Encompasses the mathematical field that allows us to organize, summarize, describe and interpret
different forms of information
data (singular datum)
Mathematical formulas and calculations to understand both small and large sets of information
Types of Data
qualitative, quantitative, discrete, continuous
Variable
Characteristics that can change in value
qualitative(categorical) variable
Variable measures in non-numerical terms, using labels or categories and are discrete. Ex. Religion,
cancer dx
quantitative variable
Variable measured in numerical terms, can be discrete or continuous. Ex. Temperature/ number of
patients in hospital
Discrete variable
Variable that can be organized into separate categories or counted using whole numbers
Continuous variable
Involves measuring where the value can take on fractional or decimal values in between two
Select qualitative variables:
Floor number in a skyscraper
Model if car
Zip code
Blood type
All are correct
Select all true statements
1. Stats are used to organize and summarize data.
2. Stats are used to interpret info
3. Stats allow inferences to be drawn about a sample group
4. Stats must be handled responsibly
