"2 to the ok rule" formula - ANS-2^k>n
"gaps" in statistics - ANS-discrete
# of youngsters (variable) - ANS-discrete
# of lessons pronouncing - ANS-"2 to the ok rule"
# of patients seen - ANS-ration
A degree of place, consisting of the mean or the median, only describes the center of the
information. It is valuable from that standpoint, however it does now not tell us whatever about
the spread of the information - ANS-dispersion
Calculate elegance c program languageperiod - ANS-2^ok>n
i≥(H-L)/okay
Calculate range - ANS-highest value - lowest price
classify commentary in step with 2 identifiable characteristics - ANS-contingency table
coefficient of variant formulation - ANS-s/x`(100%)
changing a frequency distribution to relative frequency - ANS-class frequency/total # of
observations
statistics organized in some order however the differences between records values can't be
determined - ANS-ordinal
distance to class - ANS-ratio
dress length - ANS-interval
examples of dispersion - ANS-range, suggest deviation, variance and widespread deviation
For a symmetrical, bell-fashioned frequency distribution, approximately 68 percentage of the
observations will lie inside plus and minus one popular deviation of the suggest; about 95
percent of the observations will lie inside plus and minus two preferred deviations of the
suggest; and almost all (99.7 percent) will lie inside plus and minus 3 fashionable deviations of
the imply. - ANS-empirical rule
