how do you figure out the lower quartile if there are 47 pieces of data. i know you divide it by 4 and get 11.75. but how do you know which piece of data is the 11.75th piece??? im really confused. can you just find the 11th and 12th, add then and divide by 2. or divide by 0.75??
please its due tomorrow and i forgot to do this
please its due tomorrow and i forgot to do this
