2. Types of Data ◦ Qualitative Data – Not given numerically ◦ Example – Favorite color, place of birth, favorite food, et. ◦ Quantitative Data – Given numerically ◦ Two Types – Discrete Data and Continuous Data ◦ Discrete Data – Specific numeric values ◦ Example – Shoe size, number of brothers, number of cars in a parking lot ◦ Continuous Data – Any numerical value ◦ Example – Height, mass, length

3. Vocabulary LineGraph Type of chart which displays information as a series of data points called 'markers' connected by straight line segments. BarGraph A diagram in which the numerical values of variables are represented by the height or length of lines or rectangles of equal width.

4. Vocabulary CircleGraph A type of graph in which a circle is divided into sectors that each represent a proportion of the whole. Histo- gram A diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval. What’s the difference between a bar graph and histogram?

5. Vocabulary Scatter -plot A graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present. Box- and- Whisker A graphic way to display the median, quartiles, and extremes of a data set on a number line to show the distribution of the data.

6. Vocabulary Stem-and- Leaf A plot where each data value is split into a "leaf" (usually the last digit) and a "stem" (the other digits). Frequency Table A table that shows the total for each category or group of data.
