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
andsoccer_heights
to find out! - What is the average rating for attacking players (
'A'
)?
Other variable types In the previous exercise, you worked with two Python data types:
int, or integer: a number without a fractional part. savings, with the value 100, is an example of an integer. float, or floating point: a number that has both an integer and fractional part, separated by a point. growth_multiplier, with the value 1.1, is an example of a float. Next to numerical data types, there are two other very common data types:
str, or string: a type to represent text. You can use single or double quotes to build a string. bool, or boolean: a type to represent logical values. Can only be True or False (the capitalization is important!).
