SUCCESS)
histogram for numerical data - answer used to display univariate,
NUMERICAL DATA for larger data sets (looks like a bar graph, but no
spaces) almost always results from counting. Observation is often a
whole number
histogram for continuous data - answer used to display continuous
data- values are no longer just whole numbers (class intervals)
small data set- 5 to 10 intervals
large data sets- square root n
round up
- 15 to 20 ----> 15 to <20
unimodal - answer one peak
bimodal - answer two peaks
