Compare sampling and bootstrap means
To make calculation easier, the distributions from the previous exercise have been included in tibbles. mean_popularity_2000_samp
is in the sample_mean
column of sampling_distribution
, and mean_popularity_2000_boot
is in the resample_mean
column of bootstrap_distribution
.
spotify_population
, spotify_sample
, sampling_distribution
, and bootstrap_distribution
are available; dplyr
is loaded.

Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Calculate the true population mean popularity
pop_mean <- ___
# Calculate the original sample mean popularity
samp_mean <- ___
# Calculate the sampling dist'n estimate of mean popularity
samp_distn_mean <- ___
# Calculate the bootstrap dist'n estimate of mean popularity
boot_distn_mean <- ___
# See the results
c(pop = pop_mean, samp = samp_mean, sam_distn = samp_distn_mean, boot_distn = boot_distn_mean)
