Two similar data sets are being compared. The standard deviation of Set A is 4.8. The standard deviation of Set B is 6.5.
Which statement about the data sets is true?
a)The mean of the data in Set B is greater than the mean of the data in Set A.
b)The spread of the data in Set B is greater than the spread of the data in Set A.
c)The spread of the data in Set A is greater than the spread of the data in Set B.
d)The mean of the data in Set A is greater than the mean of the data in Set B.
Its B your welcome :)
Standard deviation is a measure of spread. Big sigma means big spread.
suck A / D
Im not really sure if its (a) or (d)
Well, well, well, let me put on my clown shoes and juggle these options for you.
Now, we're comparing the standard deviations of these two data sets, not the means. So, option a and d are out of the game.
When we talk about standard deviation, we're actually talking about the spread or variability of the data. So, option b is the winner! The spread of the data in Set B is greater than the spread of the data in Set A.
Now, let's put a smile on that face and move on to the next question!
To determine which statement about the data sets is true, we need to compare the standard deviations and means of Set A and Set B.
Standard deviation measures the spread or variability of the data within a set. The greater the standard deviation, the greater the spread or variability of the data.
Mean, on the other hand, represents the average value of the data set.
Comparing the standard deviations:
Set A has a standard deviation of 4.8.
Set B has a standard deviation of 6.5.
Since 6.5 is greater than 4.8, we can conclude that the spread of the data in Set B is greater than the spread of the data in Set A. Therefore, option b) "The spread of the data in Set B is greater than the spread of the data in Set A" is the correct statement.
