Drawn from a much larger body of measurements
sample
How many steps are needed to achieve the objective of inferential statistics
5
Set of measurements
Data
Single Variable is measured on a single experiment unit
Univariate
Measure of quality and characteristics
Qualitative
population
What is the first step to achieve the objective?
Specify the questions to be answered and identify the population of interest.
More than two variables are measured
Multivariate Data
Results when two variables are measured on a single experimental unit
Bivariate Data
Measure a numerical quantity or amount on each experimental unit.
Quantitative
The individual or object on which a variable is measured.
Experimental Units
A characteristic that changes or varies over time and/or for different individuals or objects under consideration.
Variable

What are the two statistical tools what will be used in this book?
Mini Tab and Microsoft Excel
Unusual Measurements
outliers
Powerful tool for data analysis in many different fields of application
Statistics
Procedures used to make inferences about a population
inferential statistics
What does SAS stand for?
Statistical Analysis System
When a greater proportion of the measurements lie to the right of the peak value.
Skewed to the right
Skewed to the left
Consists of procedures used to summarize and describe the important characteristics of a set of measurements.
Descriptive statistics
What is the goal of a sample?
Answer Questions about a population
A variable that can assume an infinite number of values corresponding to points on a line interval is called
continuous
If the variable can take only a finite or countable number of values it is?
Discrete Viable
