Your first for loop
To make sure you fully understand what you've just done, let's try running a smaller version.
To help you remember the syntax, initialization was done with the rep() function: rep(NA, n).
And this is how you do a for loop:
for (i in 1:n) {
...
}

Data Analysis and Statistical Inference
Exercise instructions
- Initialize a vector of 100
NAs calledsample_means_small. - Run a loop for 100 times that takes a sample of size 50 from
areaand stores the samplemeaninsample_means_small.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# The ames data frame and area and price objects are already loaded into the workspace
# Initialize the vector to store the means in:
sample_means_small <-
# Run your for loop:
for (___) {
}
# Print the result:
sample_means_small
