using the data we're going to be conducting all or replying all of the other things of the interquartile range the first thing I like for you to do is to put your data in order always put it in order it will make life so much easier for you so yeah I'm going to put it in order works small to large or ascending means to go from small to large the smallest data point is 5 the. So I account for it at 7 89 89 89 turn on Bluetooth 93 so now I'm going to make sure I count the original AB 1 2 3 4 5 6 7 8 9 10 11 check on my order from a sending one two three four five six seven eight nine 10 11 so I know I have it done so now I'm going to 8 mi in a quartile box rate my limits or extreme and my whiskers I know that this is going to be my for sure I know this has to be a maximum name this is my q1 quartile one and my work out and somewhere in here we're going to have the your medium rare medium so for right now I'm just going to put a line gear and put median and I may have to readjust and move it closer to one or the other depending on what the answer is okay and that's why the minimum is defined by minimum is defined as what how do you put in an order in ascending order what is the smallest number what is your maximum been if putting your data in order what should we find next it's a fairly easy pay for and I'm going to find the exact middle right so if I have 11 I know if I look at my fingers off the middle so I can talk to the 6112 4 5 6 9 10 1 2 3 4 5 6 92 has to be your cooler how cold is median should I be start playing this 92 that I am going to use a different color and underline the left side of the median there it is q1 the lower quartile again just like we did with a median we found the middle I'm only going to find the middle of what I just on the line on the left side of the media since we have five 1 2 3 count against you if it matches 123 there it is so I'm going to circle this one can read and that that's why you weren't so 83 miserable how many data sets do I have to the right of my median the middle number between 31 that's if it matches coming back once you three so 93 has to be your cue 3090 all right now in Roswell I'm in the middle of class nothing just text her back so I'm in the middle of a video recording right now with mr. Roswell thanks love you all right so now we got pretty close to this and now you can readjust my median I know where my q1 is located 23 is located I need three. I'm just going to erase this and I'm going to read position this little closer as a 90 two and write it so this is my true representation of my visual of my interquartile range now I can go and start writing is my minimum what is my maximum what is my range what is my mode what is the i.q. our man what is my mean we've already identified because the label everything as we went it's Billy simple minimum has 85 write my maximalism 98 great it says rain the largest mass the smallest are the quartiles awesome so I paid 98 - 85 equals 3rd range by definition to 9292 and underline this in purple this is my work I purple you can see that I have the same data point three times that was repeated and I was more than any other data points so unlined it so you can see the color code gnashing you are minus the one you want to thank you mr. And what is my Q3 89 + 6 if you add it it'll outside out of the courthouse range Teyana Taylor Bala dated you on that one mr. Hicks what's another reason why we're surprising because it's because it's a range cuz it says interquartile range and the word range we said so is it go bad it is the process of subtraction of the island and a load limits and this one is the quartile that's what the IQ interquartile this is a quartile the Box part together is the only they quartile range and that's why I was a tracking okay so please do not mess up on your simple calculation that's a fraction if you have difficulty on Summer simple one and you're just having a mental laugh just take it from the lower 89 in this example and count up words so 90 and 1/2 90 so the answer has to be man the meme / / how many how much they are there is the data points and now we divided by the quantity of the point so now because if the Roswell is such a math wizard I've already did this mentally in my head and said I'm going to add all of the open gather and I was able to get what 1300 1003 1003 Adele 1003 1003 Madison Rec so my I saw some all data points were set used word 1003 I'm not 1,000 a it trust me because I use the couch I mean I talk to you later I knew I called it 3 is divided by the quantity of all my data 11 just to keep things organized and then we always want YouTube Tom of your math teacher is moving for Mesa hey we want everything to the hundred everything to the Thousand maybe ten thousand or a hundred thousand but you guys will be able to use calculator in high school so I'm just going to make sure we keep doing it in the traditional form so 11 can go into 1 how many 000 * 10 0 * 11 can go into 109 * 99 99 subtract 1 and when we subtract we get one bring down my 3 and 13 is 39 a placeholder zero I'm going to 21 time which is 9 p.m. keep going but I will give you a guideline as to how far to go to Parker stop talking alright thanks if you have a question just Call My Name when I divide it out my son by 11 my data point I was able to receive 91 basketball 18 is the mean which is another word for average so these are the different things that your assessments could ask based on the original Dana Point what is the minimum what is the maximum what is the quartile one lower quartile is there something else you want what is the upper quartile or what is the range what is the mode what is the interquartile range what is the mean or the average yeah there's 9 questions that they ask for I'm just this one day at a time I gave you so this is the reason why I'm asking you to go practice with your homework random generator or the dice Disney on campus and keep practicing these data points I'm going to use I will use it for histogram I'm going to use it for your stem and leaf as well somehow I'm going to incorporate that into the Scatter Plots as well so all these different things that we are asked to do in my class and there's a reason so this again is the interquartile range hopefully everybody made a hundred turn this off
