You have five quantitative variables and two categorical variables in a dataset. You would like to examine the pairwise relationship between all variables in the dataset.

A) What kind of plots or tables are you going to use and why?

B) How many unique correlation coefficients r are you expecting to calculate? Show your reasoning/calculations.

Answer #1

we have 5 Qauntitative variable and 2 catagarical variable, we want to check pair wise relation

A)we use scatter plot :

we can check relation between two variables in scatter plot..

and relation between atrribute we can drow contengency table.( for chi-square)

B) correlation:

Correlation is usually defined as a measure of the linear relationship between two quantitative variables (e.g., height and weight)

we have 5 quantitative variable suppose ( A,B,C,D,E). we can draw correlation matrix 5*5,each variable pair with each variable,

number of coor is

using nCx= n! /(n-x)! x! formula n= total number, x number of pair.

5C2= 5! / (5-2)!2!

=5! / 3! 2!

=5*4*3*2*1/ 3*2*2

=5*4/2

=20/2

= 10

in 5 variable we can calculated 10 different corr. we use combination because corr(A,B) = corr(B,A) boths meanings are same.

9. A lot of corn grows in Iowa. For several years, farmers have kept track of the amount of rainfall (in inches) and the amount of corn produced (in bushels per acre). A strong and linear relationship has been observed between these variables. When a regression equation is constructed in order to predict amount of corn produced based on rainfall, it is found that the equation has an intercept of 89.54 and a slope of 0.13. We can conclude from...

1.) One tailed test or two tailed test? You are performing a hypothesis test for the mean sample weight of your fellow Intro to Statistics students. For your null hypothesis , the hypothesized mean weight for the entire campus student body is 165. You have no reason to know for your alternative hypothesis whether the actual mean weight for the entire student campus body is more or less than 165. So you decide to make your alternative hypothesis as not...
