This plot is used to find the relationship between two independent variables
What is a two-way scatter plot?
A chart that compares different categories of data using rectangular bars that represent the value of the data.
What is Bar Graph?
Data type where the variables have natural, ordered categories
What is ordinal data?
The middle of the two sections before and after the median
What is quartile 1 and quartile 3?
In diagnostic test, it is the ability to correctly identify people who actually have a disease or condition
what is sensitivity of a diagnostic test?
The probability that a test will return a negative result given that the person is truly free of the disease.
What is specificity?
the total proportion or percentage of people in a specific population who have that disease at a given time
what is prevelance of the disease?
In Bayesian statistics, these two terms describe your calculated probability of an event before and after new evidence is introduced.
What are prior and posterior probabilities?
It involves asking current research participants to help identify other potential subjects for a study
What is snowball sampling?
Single stage and two stage
What are the two types of cluster sampling?
Where each member of the population has an equal chance of being selected
What is a simple random sampling?
sampling method where researchers select members of the population at a regular interval
What is systematic sampling?

"Denoted by the letter p, this is the constant likelihood of a favorable outcome occurring in each independent trial."
What is the probability of success?
In a Poisson distribution, this parameter represents both the mean and the variance.
What is λ (lambda)?
a special bell-shaped probability curve where the mean is 0 and the standard deviation is 1.
What is standard normal distribution
This parameter determines the exact shape and tail thickness of the t-distribution.
What are degrees of freedom?
