To calculate mode we first need to organize our data in numerical order Select one: O True O False To construct a frequency polygon, the class midpoint and the class frequencies are needed. Select one: O True O FalseThe class midpoint is obtained by adding the upper and lower limits. Select one: O True O False The set of all possible outcomes of a probability experiment is called sample space Select one: O True O FalseThe sum of probabilities of the events in the sample space is 100%. Select one: O True O False The number of observations in a particular class interval is called the class O midpoint O ogive O frequency O interval
