Measures of variation: <span> ways to describe measures of central tendency for a data. <em> </em><em>the most common measure of variation is range, so in this case, the smallest number is 1, and the largest is 17. This means the range is 16. </em> Interquartile Range:
<em>Lower q: {1, 2, 4} </em><em>Upper q: {8, 12, 17} </em>Here you have to subtract 12 from 2, which gives you 10.
Mean absolute deviation: Alright, let's first find the mean... (1+2+4+5+8+12+17) ---------------------------= 7 7
What is the distance of each number from 7? 1: 6 units 2: 5 units 4: 3 units 5: 2 units 8: 1 unit 12: 5 units 17: 10 units
After adding all of these together, and dividing by 7, you will get...
<em>4.571428 </em></span>≈ <em>4.6 or 5. </em><span> I hope these answers help you! Please give me brainliest!</span>
