Create three sets of bivariate variables for which you believe a relationship might exist. For each situation: Identify the explanatory variable. (1 point) Identify the response variable. (1 point) Describe the suspected relationship. (2 points) An example: Explanatory variable: Parents socioeconomic status Response variable: SAT score Explanation: I believe that if we obtained data on these variables, we might find that students of wealthier parents tend to have higher SAT scores. This may be because their parents are more educated, have more books around the house, or a variety of other reasons.

Dang spam xD
do do you have any data sets...? bivariate means you need to connect 2 things so the data is in pairs, that can be plotted on the number plane... so things like (person's height, their arm span) maybe get 10 of those measures and plot them maybe height and shoe size then something else... but you can't do anything until you have the data, and plot the points in each set.
There is nothing more. Only the question above. @campbell_st
well it asks you to create the data sets... so you need to go and ask people if you can take some measurements... 1st step is to get your 3 data sets... and only then can you look at answering the questions.
Okay measurements of what? @campbell_st
so to get a set of data find 10 people or more people and 1. measure their heights then measure their arm span record the data in pairs e.g. John: height arm span you'll need to same units so measure in inches or centimetres next set 2: height and shoe size record it in pairs Set 3 last exam result in maths and hours of study each week on maths... put the data into an excel spreadsheet and create a scatter plot.... so in terms of height and arm span Explanatory: height Response : Arm Span Suspected relationship: there is a strong positive correlation between a person's height and arm span. The taller you are the closer your arm span is to your height... that's what they are looking for the scatter plot will allow you to see if there is a connection... and then you can determine if its linear or something else... its a big thing that can't be done on here.... but 1st you need to define what data to collect and then go and get it
