4 and 5 are right, but 2 isn't because consonants are the opposite of vowels. So, you wouldn't use a or e.
The measures of spread include the range, quartiles and the interquartile range, variance and standard deviation. Let's consider each one by one.
<u>Interquartile Range: </u>
Given the Data -> First Quartile = 2, Third Quartile = 5
Interquartile Range = 5 - 2 = 3
<u>Range:</u> 8 - 1 = 7
<u>Variance: </u>
We start by determining the mean,

n = number of numbers in the set
Solving for the sum of squares is a long process, so I will skip over that portion and go right into solving for the variance.

5.3
<u>Standard Deviation</u>
We take the square root of the variance,

2.3
If you are not familiar with variance and standard deviation, just leave it.
A and D i think.(sry this needed to be 20 characters long)
No, 1/2 is bigger than 1/3 because:-
1/2 = 3/6
1/3 = 2/6
Compare
3/6 is larger, which means 1/2 is larger since they both equal each other.
Answer: 1/2 is greater than 1/3
