Question

Determine the mode and range of 7,6,5,8,8,7,3,1,1,2,3,4,5,7,7,8​

Answer 1

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

Answer 2

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.

$\implies \large \underline{ \boxed{ \tt{ \green{Mode = 7}}}}$

$\therefore\underline{\sf{Mode \: of \: the \: above \: data \: is \: \bf 7}}$.

Range:

Range can be calculated as :

• Highest number - Lowest number

So, here :

• Highest number = 8
• Lowest number = 1

Substituting values,

$\implies \tt \: Range = 8 - 1 \\ \\ \implies \large\underline{ \boxed{ \tt{ \pink{Range = 7}}}}$

$\therefore\underline{\sf{Range \: of \: the \: above \: data \: is \: \bf 7}}$.
