1. “Write down everything you know or comes to mind about the following term?
bivariate

2. 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)

3. 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.

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

5. 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

6. A two way table shows data that pertain to two different categories.

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.

7. 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?
= 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.
