In this exercise, nosotros encompass around basics on frequency tables. We besides briefly expect at chi-square exam for independence to give away relationships of 2 variables. Before proceeding, it mightiness live on helpful to expect over the attention pages for the
table, summary, and margin.table functions. Answers to the exercises are available here.
If yous obtained a dissimilar (correct) respond than those listed on the solutions page, delight experience gratuitous to post service your respond equally a comment on that page.
Exercise 1
utilisation the
utilisation the
attach() command to charge the trees dataset inward R Exercise 2
Use the
Use the
table() command alongside the arguments: trees$Height together with trees$Volume. This volition generate a two-way frequency table. Store this inward variable mytable. Exercise 3
If yous are familiar alongside excel pin tables, hence yous volition know this function. Use the margin.table( ) role to snuff it the Height frequencies summed over Volume
If yous are familiar alongside excel pin tables, hence yous volition know this function. Use the margin.table( ) role to snuff it the Height frequencies summed over Volume
Exercise 4
Use the
Use the
margin.table( ) function to snuff it the Volume frequencies summed over Height. Exercise 5
Now utilisation the
Now utilisation the
table() function 1 time again precisely using all the features of the trees dataset, that includes girth, summit together with volume. This volition impress out a multidimensional iii means frequency table. Exercise 6
Suppose yous convey a variable ‘a’ that stores a 2d sample of heights of trees.
Use the cbind() to add together the a column to your trees dataset. Store the results dorsum into trees.
Suppose yous convey a variable ‘a’ that stores a 2d sample of heights of trees.
a=c(70, 65, 63, 72, 80, 83, 66, 75, 80, 75, 79, 76, 76, 69, 75, 74, 85, 8, 71, 63, 78, 80, 74, 72, 77, 81, 82, 80, 86, 80, 87)Use the cbind() to add together the a column to your trees dataset. Store the results dorsum into trees.
Exercise 7
Now do a 2 means frequency tabular array betwixt Height together with a equally the arguments. Store this tabular array inward mytable_2.
Now do a 2 means frequency tabular array betwixt Height together with a equally the arguments. Store this tabular array inward mytable_2.
Exercise 8
Use the margin.table() role 1 time again from Q3 together with snuff it Height frequencies summertime over a. What differences do yous give away from the results of Q3.
Exercise 9
Chi Square exam for independance:
a)Print the results of the summary() role on mytable. Note the Chi Square exam for independance results together with P value
b)Print the results of the summary() role on mytable_2. Note the Chi Square exam for independance results together with P value.
Chi Square exam for independance:
a)Print the results of the summary() role on mytable. Note the Chi Square exam for independance results together with P value
b)Print the results of the summary() role on mytable_2. Note the Chi Square exam for independance results together with P value.
Exercise 10
