3.7 Flashcards
bell curve/normal distribution
a measure of variation (or variability) that indicates the typical distance between the scores of a distribution and the mean.
descriptive statistics
used by researchers to summarize and “describe” data found during research
inferential statistics
provide ways of testing the reliability of the findings of a study and “inferring” characteristics from a small group of participants or people (your sample) onto much larger groups of people (the population)
measures of central tendency
(mean, median, and mode) are statistics that describe the center of a data set.
measures of variability
statistics that describe the amount of difference and spread in a data set.
significant difference
a difference in 2 models that are different being compared to each other.
statistical significance
the probability of some result from a statistical test occurring by chance
skewed distribution
a statistical term that measures “asymmetry” (lack of similarity) in a “bell curve”
standard deviation
a measure of variation (or variability) that indicates the typical distance between the scores of a distribution and the mean.
