### Statistika

(intro. to Statistics)

We muddle through life

Making choices based on

Incomplete information

We muddle through life

Making choices based on

Incomplete information

This is not just a matter

of ordering soup!

Statistics also

Involves matters of

Life and Death

Ex. mean, median, modus, etc.

Ex. hypothesis testing, analysis of variance, corelation, regression, etc.

Ex. body temperature is a variable that changes over time within a single individual; it also varies from person to person. Religious affiliation, ethnic origin, income, height, age, and number of offspring are all variables—characteristics that vary depending on the individual chosen.

Ex. body temperature is a variable that changes over time within a single individual; it also varies from person to person. Religious affiliation, ethnic origin, income, height, age, and number of offspring are all variables—characteristics that vary depending on the individual chosen.

There are several variables in this example. The experimental unit on which the variables are measured is a particular undergraduate student on the campus, identified in column A.

Five variables are measured for each student: grade point average (GPA), gender, year in college, major, and current number of units enrolled.

If we consider the GPAs of all students at this university to be the population of interest, the five GPAs in column B represent a sample from this population. If the GPA of each undergraduate student at

the university had been measured, we would have generated the entire population of measurements for this variable.
