first introduced the word "statistics"
gambler who wrote the first known study of the principles of probability
dicovered the equation for normal distribution
applied the theory of probabilty to anthropological measurements and expanded the same principle o the field of psychology and education
father of modern stats
developed the use of percentiles and contributed the application of stats to heredity
worked with Galton to develop the theory of regression and correlation
develop methods for decision-making derived from smaller sets of data
developed Fisher's test used in the analysis of variance
a single figure that is representative of the general level of magnitudes of the items in a set of data
arithmetic average of all the scores
most frequent score
central value that divides the ordered data samples into 2
describes distance of the score from the median
distance from the middle
how far above or below from the mean
same as standard but square root is not taken
distance between the highes and lowest
to describe group characteristics by collection of summarizing data
to describe a population by studying a random sample
should come from a population with normal distribution
does not require any assumption
