Session 1 Descriptive Statistics & R intro
-> “mean”
-> “median” (middle)
raw f -> “table”
relative (%) f -> “prop.table”
sort table -> “sort”, with the option
“DECREASING=TRUE” or
DECREASING=FALSE”
SD: on average, how far is each individual grade from the mean.
->small SD = little variation
->large SD = lot of variation
The standard error of the mean indicates how different the population mean is likely
to be from a sample mean. It tells you how much the sample mean would vary if you
were to repeat a study using new samples from within a single population.
The confidence interval is the range of values that you expect your estimate to fall between
a certain percentage of the time if you run your experiment again or re-sample the
population in the same way.
Boxplot “summary” will return
min, Q1, median,
mean, Q3, max.
“quantile” (0.25) will
return Q1 (first
quartile)
“quantile” (0.75) will
return Q3 (third
The IQR (Q3 – Q1) can be used as a quartile)
criteria to determine outlier observations
“IQR” will return the
inter- quartile range
(Q3-Q1).

most in-depth observational research method that studies people in their naturally occurring
environment
->advantage of this method is that it gives you the opportunity to better understand the
cultures, challenges, motivations of consumers in their natural environments.
Observation research involves documenting the actions of participants, focusing on their behavior
within a specific environment.
-> advantage of this method lies in its natural and authentic data collection experience. Consumers
behave as they normally would, without the pressure of being under study.
