Answer:
Range: 0.07
Median: 0.15
Mode: 0.15 and 0.16 (This is <u>bimodal</u>. It has 2 modes.)
Step-by-step explanation:
When you have a line and dots, that means that that number is repeated by the number of dots. So, since, 0.11 has 3 dots, when you write out all the numbers, you will write 0.11 3 times. (In the picture attached below, I have put every single number in order so you can see what I mean.)
<u>The Range</u> is the biggest number minus the smallest: 0.18 - 0.11 = <u>0.07</u>
<u>The Median</u> is the <u>m</u>iddle number: 0.15 (Look at picture)
<u>The Mode</u> is the number that occurs <u>m</u>ost <u>o</u>ften: 0.15 & 0.16
Having 2 modes is possible. They both just have to be repeated the same amount of times.
From the distribution, it seems as though the digits at fairly even frequencies, though we can test our intuition by doing a few calculations.
The mean (or average) frequency can tell us quite a bit here, and we can calculate it by adding together all of the frequencies and then dividing by the number of frequencies (in this case, 10, since we have 10 digits)
Doing that, we find
(1 + 4 + 5 + 7 + 4 + 5 + 2 + 3 + 5 + 5)/10 = 41/10 = 4.1
When we divide the number of digits (40) by 4.1, we find it equals roughly 10, which means that, *on average*, each of the 10 digits appeared about 4 times. With this knowledge in hand, it wouldn’t be too out-there to suggest that this distribution is going to tend to even out more and more as we continue to add further decimal approximations of π
