# Data available online here: https://spcls-coding-club.netlify.com/R/IntroR3.files/IntroR3_data.csv
# Challenge 1: Import the data directly from the internet (i.e. without downloading it to your Computer)
# Challenge 2: Have a look at the data to make sure it has been imported correctly and makes sense, reimport if you need to.
# Challenge 3: Generate the following summary statistics for the two 'Familiariazation_Gaze' variables:
# mean
# standard deviation
# variance
# median
# interquartile range
# Challenge 4: Visualise the data in the 'Familiariazation_Gaze' variables using the boxplot() function, see if you can get both on a single plot.
# Challenge 5: Run a paired t-test to see if there is a significant difference between the two variables
# Note: Using a formula won't work here, can you work out why and how else can you do it?
# Extra challenge: Try and remove the outliers from the data set
# (hint: when indexing you can use tests to select cases,
# eg. to find observations in 'example_variable' greater than 200 you'd use: example_variable > 200 )
