    Explore Datasets

    Use the arrays imported in the first cell to explore the data and practice your skills!

    • Print out the weight of the first ten baseball players.
    • What is the median weight of all baseball players in the data?
    • Print out the names of all players with a height greater than 80 (heights are in inches).
    • Who is taller on average? Baseball players or soccer players? Keep in mind that baseball heights are stored in inches!
    • The values in soccer_shooting are decimals. Convert them to whole numbers (e.g., 0.98 becomes 98).
    • Do taller players get higher ratings? Calculate the correlation between soccer_ratings and soccer_heights to find out!
    • What is the average rating for attacking players ('A')?


    ls - list of current files in directory ls -a - shows ALL(included hidden) files and directories

    pwd - returns current directory name cd <dir_name> - move to <dir_name>

    echo "Contents of a new file" > new_text_file.txt echo "Append to file" >> old_text_file.txt

    nano <file_name> - edit file Ctrl+O - save changes Ctrl+X - exit the editor

    git add git add .
    git commit -m "Comment ..."
    git status

    git diff filename git diff -r HEAD filename git diff -r HEAD
