Graded A+
population ✔Correct Answer-the largest collection of entities for which we have an interest at
a particular time, defined by our sphere of interest
parameter ✔Correct Answer-characteristics or measure obtained from a population
sample ✔Correct Answer-a subgroup or subset of the population
statistic ✔Correct Answer-characteristic or measure obtained from a sample
biostatistics ✔Correct Answer-the application of statistical methods to biological organisms
epidemiology ✔Correct Answer-the study of the distribution and determinants of health-
related events and states of being within a specific population
descriptive statistics ✔Correct Answer-summary of the characteristics of the data set
gathered while collecting information from the study sample
inferential statistics ✔Correct Answer-data is used to make inferences about the larger
population as a result of utilizing different statistical analysis tools on the data collected
variable ✔Correct Answer-characteristics or attributes that can assume different values (it
varies depending the person, place or thing categorized)
categorical ✔Correct Answer-the values represent a quality or trait of a subject by which they
can be grouped (hair color, types of exercise)
dichotomous data ✔Correct Answer-data from outcomes that can be divided into two
categories (e.g. dead or alive, pregnant or not pregnant), where each participant must be in one
or other category, and cannot be in both
ordinal data ✔Correct Answer-data exists in categories that are ordered but differences
cannot be determined or they are meaningless. (Example: 1st, 2nd, 3rd)
nominal data ✔Correct Answer-data of categories only. Data cannot be arranged in an
ordering scheme. (Gender, Race, Religion)
, continuous data ✔Correct Answer-the values represent how much or haw many of something
a subject has
interval data ✔Correct Answer-Differences between values can be found, but there is no
absolute 0. (Temp. and Time)
ratio data ✔Correct Answer-data with an absolute 0. Ratios are meaningful. (Length, Width,
Weight, Distance)
mean ✔Correct Answer-the average value
median ✔Correct Answer-The middle value in a data set
mode ✔Correct Answer-the most common value
range ✔Correct Answer-the difference between the lowest and highest value
probability ✔Correct Answer-a proportion that is the number of observations of interest over
the total number of observations
probability formula ✔Correct Answer-# of individuals with a characteristic/ total # of
individuals sampled; be a value between 0-1
simple probability ✔Correct Answer-looking at a single variable
prevalence ✔Correct Answer-number of people with a condition out of the entire sample
incidence ✔Correct Answer-number of new cases of a condition divided by the total number
of people at risk for the condition
simple random sample ✔Correct Answer-every member of the population has a known and
equal chance of selection
systematic sample ✔Correct Answer-a sample drawn by selecting individuals systematically
from a sampling frame
stratified sample ✔Correct Answer-a sample drawn in such a way that known subgroups
within a population are represented in proportion to their numbers in the general population
binomial distribution ✔Correct Answer-based upon a dichotomous outcome- only 2
outcomes can occur
normal distribution ✔Correct Answer-used to model the distribution of a continuous variable;
is unimodal and symmetric
