Presentation Transcript

• 1.

• A collection of objects with various attributes can be classified or sorted in different ways.

• A single object can belong to more than one class. Classification is the first step in the organization of data.

• 2.

• Data are gathered and organized in order to answer questions about populations from which the data come.

• With data from only a sample of the population, inferences are made about the population.

• 3.

• Different types of graphs and other data organizations provide different information about the data and the population from which the data are taken.

• The choice of graphical representation can impact how well the data are understood.

• 4.

• Measures that describe data with numbers are called statistics.

• Data can be organized in various graphical forms to visually convey information.

• The use of a particular graph or statistic can mediate what the data tell about the population.

• 5.

• Both graphs and statistics can provide a sense of the shape of the data, including how spread out or how centered they are.

• Having a sense of the shape of the data is having a big picture of the data rather than a collection of numbers.
