Statistics/ Data analysis
Box plots
you find box plots by finding the median then find the median for the upper quartile and lower quartile
I.Q.R
an example is upper quartile-lower quartile
I,Q,R is the range from the internal quartile range
Statistical questions
an example for statistical questions are ''how much on average do professors get paid at UCONN'' It is a Statistical because it says professors instead of professor and it say average.
what was the average temperature of this year It is a Statistical because it says what was the AVERAGE TEMPERATURE ans when it says of THIS YEAR
How many bikes are bought during 2019 and 2020 it is a statistical question because it says how many Bikes and not just bike and also because it say during 2019 and 2020
Central tendency
median The median is in the middle step 1 arrange the number in order from least to greatest step 2 then find the middle number your number in the middle is your median step 3 if there is two middle numbers find the mean of these two numbers. an example is 111122223333444445555 and the median is 3 you use this when you are finding the median
mode Is the number that shows up the most the step for the mode are you look at all of the numbers and you put them into least to greatest and say like this 13225682 and put it in order so it would be like 1223568 and then you see how many numbers there are the most so it would be 2 because that is the most that show up and there is three of them so that would be the answer.
Mean The mean is the average The first step is add all of the numbers step 2 is divide the sum by the number of the addend an example is 1111 and the mean is 1 you can use this when you are finding the average of test scores
Range The range is where you get the number and the end and the one at the beginning and you subtract them and then you get your ANSWEr
an example for mode is 1,1,1,1,1,2,2,3,4,5, and the mode is 1 because there are multiple 1.
HISTOGRAMS you have to get you numbers like 2,3,2,8,5,10,4,6,1,4,7,5,3 then you would make a diagram that looks like this
So what they are doing they are put it in order so say like 1-2 and 3-4 and 5-6 and 7-8 and 9-10 and then you put it in order from one to ten and there would be 2 1-3 and 4 3-4 and then 3 5-6 2 for 7-8 and there is 1 9-10.
line plots
line plots show the frequency of data
an example is
