For my IXL I’ve been learning about data, but for this specific IXL it was mean, median, mode and range. While doing the IXL I found it a bit difficult to understand what mean, median and range mean so I got a few incorrect but after looking at how I should answer the questions I realised how to do it! For mean, you add all the numbers together and divide from the numbers there for example. :
5 4 5 5 7 5 3 /// add those numbers together and divide by how many digits are there so
5+4+5+5+7+5+3 = 28 , Now divide by how many digits are there so : 7 now 28 divided by 7 = 4 and that’s the answer.
But that’s just one example, here’s the example for Range and Mode
Mode is the second easiest and range being the first easiest Ill show you why : Mode means the most consistent or frequent / common number that shows. Here’s a math example :
2 2 1 2 4 5 7 4 7 2 /// The mode here for this example would be 2 since its the most frequent one and shows up the most
Range : Range is the easiest one because it’s very simple all you need to do is find the highest number and subtract that number by the lowest number. Here’s an example :
9 3 4 5 4 2 4 5 6 /// The range for this example would be 9 – 2 because 9 is the highest number and 2 being the lowest. Now after subtracting you’ll get your answer which would be 9 – 2 = 7, so the range is 7!
Median : Median is quite easy all you have to do is sort all the numbers from lowest to highest and the number in the middle is the Median here’s an example :
7 5 5 6 4 6 4 2 1 3 8 9 /// After ordering them from lowest to highest here’s what it should look like :
1 2 3 4 4 5 5 6 6 7 8 9 , The Median would be 5. This one isn’t the hardest but its ranked 3rd difficulty just above mean as median is quite tedious. In case of Two numbers being in the middle, add them together and than divide by 2. There will be your answer.
