Intro to Summary Statistics
summary statistics - correct answer-collection, evaluation, and interpretation of data,
statistical analysis of measurements can verify the quality of a design process
central tendency - correct answer-mean, median, mode
Variation - correct answer-spread of values around the center
range, standard deviation, IOR - correct answer-examples of variation
distribution - correct answer-summary of the frequency of values
frequency tables, histograms, normal distribution - correct answer-examples of distribution
mean - correct answer-sum o values divided by number of values in the set
ONLY AT THE END - correct answer-when do you round
mode - correct answer-the most frequently occurring score(s) in a distribution
B - correct answer-symbol of mode
Bimodal - correct answer-two modes
Multimodal - correct answer-more than two modes
median - correct answer-the middle score in a distribution; half the scores are above it and
half are below it
x, pronounced x tilde - correct answer-symbol of median
range - correct answer-the difference between the highest and lowest scores in a distribution
r - correct answer-symbol for range
standard deviation - correct answer-measure of the spread of data values, larger indicates
wider spread
standard deviation formula - correct answer-the square root of the variance
Histogram - correct answer-common data distribution chart used to show frequency with
which specific values occurs in a data set
intervals - correct answer-large number of groups divided into limited number of groups
