Below is the sample of baby deliveries in an 8 hour period at a small hospital:
13 14 6 12 13 8 6 14 4 7
8 7 5 9 10 8 3 5 7 6
7 10 10

From this data set, compute the sample mean, median, mode and midrange. Compute the 1st
quartile and 3rd and interpret their meanings.

Dude you better hand me best answer, here goes, first arrange data from lowest to highest,you'll then have 345566677778889,10,10,10,12,13,13,14,14 okay now mean is the total of them(add them all, divided by how many they are)so mean =192/23=8.35 to one decimal place.median is n+1/2 which in this case is 23+1 divided by 2 which means the median number is the 12th value which is 8, mode is the most frequent one,in this case that's 7,midrange is (not so sure on this one)highest value plus lowest value,all divided by 2 for you thats (3+14)/2=8.5, first quartile Q1=1/4n where n is the number of items or figures which for you is 23, so Q1=1/4(23)=5.75 rounds to 6,so the 6th figure is 6,therefore Q1 is 6, third quartile Q3 also known as upper quartile is given by 3/4n,for you Q3 =3/4(23)=17.25 take it up to 18,which is 10(from ordered list).the lower quartile means the bottom 25% of your data,it follows that q3 would be the top 25% of your data
