Imma Scope the Scenery Out
The science of ________ deals with the collection, analysis, interpretation, and presentation of data.
Statistics
categorizes data based on similar characteristics
Qualitative (categorical)
The simplest/most commonly used sampling method where everyone has the same probability of being chosen
Simple Random Sample
the number of times a value of the data occurs
Frequency
inactive treatment that has no real effect on the explanatory variable
Placebo
How likely it is that an event will occur
Probability
Assigns a number value to data
Quantitative (numerical)
Occurs when we use results that are readily available
Convenience Sampling
a chart that lists a set a values and how often
Frequency Table
The participants in the study do not know if they are being given treatment or a placebo
blinding
a collection of persons, things, or objects under study
Population
DOUBLE JEOPARDY: Numerical Data can be classified as __________ or ____________
Discrete/ continuous
Occurs when we divide the population into groups and then take a proportionate number from each group using SRS.
Stratified Sampling
the ratio (fraction or proportion) of the number of times a value of the data occurs in the set of all outcomes to the total number of outcomes.
Relative Frequency
Neither the participants in the study nor the researchers know if participants are being given treatment or a placebo
Double Blinding
a portion (or subset) of the larger population that is used to study the population as a whole
Sample
Visual/Graph that can only be used for percentages that are exactly 100%
Pie Chart
Occurs when we divide the population into groups and then randomly select some of the groups
Cluster Sampling
Besides frequency and it's two types, this also should be included in a frequency table
Data Value
DOUBLE JEOPARDY: ___________ is the variable that affects another while _________ is the variable that is affected
explanatory, response
Actual value of the variable that can be classified as categorical or numerical
Data
Visual/Graph that can be used for percentages that are under, over or exactly 100%
Bar Graph
Occurs when we randomly select a starting point and take every “n”th piece of data from a listing of the population.
Systematic Sampling
the accumulation of the previous relative frequencies.
Cumulative Relative Frequency
a group in a randomized experiment that receives an inactive treatment but is otherwise managed exactly as the other groups
Control Group
