Determine the mode and range of 7,6,5,8,8,7,3,1,1,2,3,4,5,7,7,8
Answers
Answer: Mode
mode-88,11,77,are mode not - 7,6,5,7,3,2,3,4,5,8
for example = The Mode
The mode is the value
which appears the most
often in the data. It is
possible to have more
than one mode if there
is more than one value
which appears the most. The data values:
2 , 2 , 3 , 5 , 5 , 7 , 8
The values which appear most
often are 2 and 5. They both
appear more time than any
of the other data values.
So the modes are 2 and 5
The data values:
2 , 3 , 3 , 4 , 6 , 7
This time there is only one value
which appears most often - the
number 3. It appears more times
than any of the other data value.
Range
for example = The Range
To find the range, you
first need to find the
lowest and highest values
in the data. The range is
found by subtracting the
lowest value from the
highest value. The data values:
2 , 2 , 3 , 5 , 5 , 7 , 8
The lowest value is 2 and the
highest value is 8. Subtracting
the lowest from the highest
gives: 8 - 2 = 6
So the range is 6
The data values:
2 , 3 , 3 , 4 , 6 , 7
The lowest value is 2 and the
highest value is 7. Subtracting
the lowest from the highest
gives: 7 - 2 = 5
Step-by-step explanation:
Answer:
- Mode of the given observations is 7.
- Range of the given observations is 7.
Step-by-step explanation:
Given :
- Observations are 7, 6, 5, 8, 8, 7, 3, 1, 1, 2, 3, 4, 5, 7, 7, 8
To Find :
- The mode and range of the given data.
Solution :
For calculating mode, firstly we will arrange the numbers in ascending order. After that, we will count the numbers which occurs maximum number of times.
Now resembling the numbers in ascending order,
→ 1, 1, 2, 3, 3, 4, 5, 5, 6, 7, 7, 7, 7, 8, 8, 8
So, here we can clearly see that 7 occurs 4 times and is the maximum observation among the given data.
.
Range:
Range can be calculated as :
- Highest number - Lowest number
So, here :
- Highest number = 8
- Lowest number = 1
Substituting values,
.
