_____consists of the collection, organization, summarization, and presentation of data.
____consists of generalizing from samples to populations, perfor- ming estimations and hypothesis tests, determining relationships among variables, and making predictions.
The area of inferential statistics called____?
_____are variables that have distinct categories according to some characteristic or attribute.
____are variables that can be counted or measured.
____assume values that can be counted.
____can assume an infinite number of values between any two specific values. They are obtained by measuring. They often include fractions and decimals.
____of a number, then, is defined as a class in which a data value would be placed before the data value was rounded.
____ classifies data into mutually exclusive (nonover- lapping) categories in which no order or ranking can be imposed on the data.

A____is the organization of raw data in table form, using classes and frequencies.
Each raw data value is placed into a quantitative or qualitative category called a___
The numbers in the sec- ond column are called___.
A _____distribution is a distribution that shows the number of data values less than or equal to a specific value
The _____s a graph that displays the data by using contiguous vertical bars
The _____ is a graph that displays the data by using lines that connect points plotted for the frequencies at the midpoints of the classes.
