Comparing Categorical data (words) Relative frequency- is the ratio of the subtotal and the total, usually report data in the form of a fraction, decimal, or percent Numerator ÷ denominator Data for two variables Comparing Categorical data (words) 2 way tables bivariate Can also be displayed on graphs Use quantitative data (numerical data/numbers)

Fraction, Decimal & Percent Decimal to percent – move decimal 2 places to the right or multiply the number by 100. Fraction to Percent– Change Fraction to Decimal by dividing 𝑑𝑒𝑛𝑜𝑚𝑖𝑛𝑎𝑡𝑜𝑟 𝑛𝑢𝑚𝑒𝑟𝑎𝑡𝑜𝑟 then moving decimal 2 places to the right or multiply the number by 100.

23 10 14 3 Foreign Language Sport School: The data from a survey of 50 students is shown in the Venn diagram. The students were asked whether or not they were taking a foreign language and whether or not they played a sport. Foreign Language Sport 23 10 14 3 I can construct two-way frequency and relative frequency tables to summarize bivariate categorical data (two variables collected from the same subjects). From two-way frequency and relative tables, I can describe interpret, and justify inferences in patterns of association between the two variables

23 10 14 3 Foreign Language Sport 37 24 How many students are taking a foreign language? How many students play a sport? How many students do both? How many students do not play a sport and do not take a foreign language? How many students play a sport but do not take a foreign language? 24 Foreign Language Sport 23 10 14 3 I can construct two-way frequency and relative frequency tables to summarize bivariate categorical data (two variables collected from the same subjects).

A two way table shows data that pertain to two different categories. I can construct two-way frequency and relative frequency tables to summarize bivariate categorical data (two variables collected from the same subjects). From two-way frequency and relative tables, I can describe interpret, and justify inferences in patterns of association between the two variables A two way table shows data that pertain to two different categories. A two way table can also show relative frequencies. Relative frequency is the ratio of the value of a subtotal to the value of the total.

Felipe surveyed students at his school Felipe surveyed students at his school. He found that 78 students own a cell phone and 57 of those students own an MP3 player. There are 13 students that do not own a cell phone, but own an MP3 player. Nine students do not own either device. What is the relative frequency of students who own a cell phone who also own an MP3 player? 57 78 = 0.73 or 73% A two way table can also show relative frequencies. Relative frequency is the ratio of the value of a subtotal to the value of the total.
