I chose these 4 videos because they clearyly eaxplain how to find the mean, median, and modeIn the first video i only paid attention to how you were supposed to find the mean. In the next video i paid attention to the median then the mode. Each video covers a certain lesson a different way thats what makes the videos so valuable. the 3rd and 4th videos explain meadian and mode in totaly different ways than the first two videos.
The videos state that the way to find the mean is too first line up all the numbers in order from least to greatest, after that they are lined up you go down the list adding all the numbers up to a total of whatever number you get. Then you divide the total number by how many numbers you have added up to get the total. For the median you just look for the number in the middle, and for the mode you you list the number or numbers that are listed more than once.
I chose this video because it elaborates how to do and use standard deviation. With a calculator, standard deviation is easy. All you have to do is press STAT then ENTER. after theat there is a list, there you put your number in the list then press STAT go over once with the arrow keys then press ENTER three times. Without a calculator i wouldnt know how to explain it very well. Quartiles, Outliers, and Data representations
I chose this video because it explains how to find the qaurtiles.
The video shows you how to find the qaurtiles in few easy steps.
First you sort your data from least to greatest. Then you will find the first qaurtile.
The first quartile is all the numbers below the median.
I chose this video because it describes specifically what an outlier is.
An outlier is an extremly high or extremly low value in the data.
According to the video, you can find an outlier if it is greater than Q3 + 1.5(IQR)
or les than Q1 + 1.5(IQR).
