Introduction to Data Visualization Watch the video and answer the questions below. You can pause and rewind the video to find the answers. Video Vocabulary Match the vocabulary word from the video with its definition. Quantitative Data quantities; numbers that have both order and consistent spacing. Categorical Data Doesn't have a meaningful order or consistent spacing. Frequency Table The simplest way to describe categorical data. Lists categories and the number of items that fall in the category. Relative Frequency frequency data points*100 - calculating the frequency as a percentage of the whole. Bar Chart uses frequencies from frequency table to create bars that have a height equal to the frequency. Pie Chart Use relative frequency of categories to portion out pieces of a circle. Pictograph Represents frequency with pictures. Histogram like a bar chart, but bars are touching because the data are continuous, gives us information about how the data are distributed. Frequency Table of Rap Songs on my IPod. Calculate relative frequency and round to the nearest percent. Make sure to put a % after your number.relative frequency = frequency number*100 Rap Songs on my iPod Frequency Relative Frequency Drake 20 18% Kanye West 10 9% Lil Wayne 18 16% 50 Cent 5 5% Jay-Z 34 31% Cardi B 23 21% Binning Quantitative Data Use the data below of ages at a family reunion to bin and create a frequency table. Calculate relative frequency of the binned data.65, 98, 70, 1, 2, 5, 18, 14, 12, 10, 15, 14, 11, 20, 10, 26, 31, 32, 31, 36, 40, 1, 45 Age Category Frequency Relative Frequency Infant (under 3) 3 13% Child (age 3-12) 5 22% Teen (age 13-17) 3 13% Young Adult (age 18-39) 7 30% Middle Age (40-64) 2 9% Older Adult (65 and over) 3 13% Graph Matching Match the graph to its type.
