controlled study: a structured study that consists of two groups, one that makes use of the subject of the study, and a control group that does not
observational study: a type of study in which the individuals are observed or certain outcomes are measured. No attempt is made to affect the outcome
population: the whole set of objects that are of interest in a study
sample: a subset of the population
univariate data: values collected for a single variable
bivariate data: values collected for two different variables
bias: an influence thataffects the reliability of a statistical measurement in some way
qualitative: descriptive data
quantitative: numerical data
mean: average set of data
mode: a value that appears most often in a list of data
median: a value in the middle of a list of data when values are arranged in order
frequency table: a table that displays the number of times each value or group of values occur in a data set
histogram: a bar graph that shows the frequency of datasets
quartile: seperate a dataset into four equal parts
five number study: Min, Q1, Median, Q3, Max
percentile: tells what percent of the total number of data values lie at or below a given measure
range: the dfference of the max and min data values
interquartile range: the difference between the first and third quartile
outliers: a data value that is great than the upper quartile plus 1.5 times the IQR or less than the lower quartile minus 1.5 times the IQR
standard deviation: the average amount by which individual data items in a data set differ from the arithmetic mean of all the data in the set
variance: a statistical measure that tells us how measured data vary from the average value of the set of data
normal curve: a symmetrical bell shaped curve that represents the distribution of values, frequencies or probabilities of a set of data
normal distribution: a set of data that can be represented by a normal curve
emperical rule: if a data set has approximately 68% of data within one standard deviation of the mean, 95% with in two standard deviations, and 99.7% within three of three standard deviations, tha data follows a normal distribution
two score: how many standard deviations a givendata value, x, is from the mean
outcome: a possible result
sample space: the set of all possible outcomes
event:a subset of the sample space
dependant event: an outcome that is affected by a previous outcome
independant event: an outcome that is NOT affected by a previous oucome
fundamental counting prinicple: used to find the number of elements in the sample space
factorial: the result of multiplying descending natural numbers(!)
permutation: a set of objects in which order matters
combination: a set of objects in which order DOESN'T matter
emperical probability: probability based on observations
theoretical probability: probabilty based on equally likely outcomes
mutually exclusive probability: events that have no outcomes in common
binomial probability: an experiment with two possible outcomes, where the probability of each outcome is the same in each repeated trial, and the occurance of one excludes the occurance of the other in any trial
binomial: a polynomial with two terms
pascals triangle: the arrangement of the binomial coefficients in a pattern of triangle. each row begins and ends with 1, and each entry is the sum of the numbers above it
binomial theorm: a method used to efficiently expand powers of binomials
rational number: a number that can be written as a fraction
undefined: the result when a number or expression is divided by zero
simplest form: a number reduced to lowest terms
proportion: an equation that states that two ratios are equal
absolute value: the distance from a number to zero on the number line
square root: one of two equal factors whose product is k
cube root: one of three equal factors whose product is k
rationalize: write an expression so there is no radical in the denominator
conjugate: change the sign between the terms of an expression
relation: a set of ordered pairs
domain: the set of all first elements in a relation
range: the set of all second elements in a relation
