Normality and outliers
to uphold the assumption of normality, verify that either the
sample size is large enough (n > 30) or there is linearity in the
normal probability plot
to verify that there are

What is Statistics?
Statistics: The science of collecting, organizing, summarizing, and analyz
Data Collection
results are presented with some measure of the amount of variability
identify the research objective
population- the group to be studied
individuals- an object within the population
Co
Inferential Statistics
population data can be difficult or even impossible to obtain
therefore, sample data are used to draw conclusions about the
population
the rest of this course will focus on how

Summarizing Data Numerically
a parameter is a descriptive measure from a population
a statistic is a descriptive measure from a sample
Measures of central tendency
mean (also called average)

Cluster sampling
when groupings (or clusters) of individuals exist
within the population, randomly select some clusters
and sample all individuals within the selected
clusters
ex: dept of agriculture
Measures of Position
Measures of position describe the relative position of a
specific data value with respect to the entire data set.
these measures include:
z- scores
used to compare values of varia

The addition rule for disjoint events
two events are disjoint (or mutually exclusive) if they have
no outcomes in common
The Venn Diagram
P (A or B) = P(A) + P(B)
Ex. One samples patients randomly
4.2 Least-Squares Regression procedure
takes into account all individual data points and minimizes the
distances between the points and the line
the LSR line minimizes the of the residuals squared

Population proportion
likely the most frequently reported confidence intervals
polls, for example, often report a that a certain proportion (or
percentage) of individuals have a certain characteristic
