for #2 so for range its; 27 -(-6)= 33
right?
for quest 3
The numbers are: (yes 2 is listed twice)
2, 1, -1, 2, 0 , -2, 4, 0
for mean is it: 6 divide by 8 = .75
for median is it: 0 and 1 as median so
0 + 1 = 1 divide by 2 = median of : .5
for mode: 2
for range: is it : 4 - (-2) = 6
For question 2:
To find the range, you need to subtract the lowest value from the highest value.
In this case, the highest value is 27 and the lowest value is -6.
So, yes, the range would be 27 - (-6) = 33.
For question 3:
Mean:
To find the mean, you need to sum up all the numbers and divide the total by the count of numbers.
For the given numbers: 2, 1, -1, 2, 0, -2, 4, 0
Summing up all the numbers gives: 2 + 1 + (-1) + 2 + 0 + (-2) + 4 + 0 = 6
The count of numbers is 8.
So, the mean would be 6 divided by 8, which is 0.75.
Median:
To find the median, you need to arrange the numbers in ascending order and then find the middle value.
For the given numbers: 2, 1, -1, 2, 0, -2, 4, 0
Arranging them in ascending order: -2, -1, 0, 0, 1, 2, 2, 4
The middle values are 0 and 1.
So, to find the median, you add the two middle values and divide by 2: (0 + 1) / 2 = 0.5.
Mode:
The mode is the value(s) that appears most frequently in the dataset.
From the given numbers: 2, 1, -1, 2, 0, -2, 4, 0
The number 2 appears twice, which is the most frequent.
Thus, the mode is 2.
Range:
To find the range, you subtract the lowest value from the highest value.
In this case, the highest value is 4 and the lowest value is -2.
So, the range would be 4 - (-2) = 6.
