Statistical Tables and Graphs Chapter 10 Unit C Statistical Tables and Graphs

Essential Questions What are some reasons for creating tables and graphs? How do we display our data effectively What are some ways that media deceives us?

Warm up: Is there a nicer way to display this data?

Definitions: Frequency: how often a data point appears Frequency table: table that displays frequency of the categories Relative frequency: frequency in category/total frequency Cumulative frequency: # of data values in the category and any preceding category

Type of Data: Qualitative data: describes qualities or categories Ex: brand names Quantitative data: represents counts or measurements Ex: heights of students

Important Labels For Graphs Title/caption Vertical scale and title (y) Horizontal scale and title (x) Legend: way to identify the individual sets

Type of Graphs: Bar Graph

Type of Graphs: Pie Chart

Type of Graphs: Histogram

Type of Graphs: Line Graph

Type of Graphs: Stacked Area Graph

Type of Graphs: Scatterplot
