19

Step-by-step explanation:

Given :

Stem   Leaves

2    |      6, 7, 7

3    |      0, 2, 3, 3, 4.

4    |      0, 5

To Find: What is the range of the data in this stem-and-leaf plot?

Solution :

Since we are given key 3 vertical line 0 equals 30.

So, in the given stem leaf plot the number are :

26,27,27,30,32,33,33,34,40,45

Now Range = maximum number   -  minimum number

Range = 45-26

Range = 19

Hence The range of the data in this stem-and-leaf plot is 19

Step-by-step explanation:

C. 19

Step-by-step explanation:

According to the given stem-and-leaf plot,

The given observation are, 26, 27, 27, 30, 32, 33, 33, 34, 40, 45

Where, in each observation, the first digit represents the stem and second digit represents the leaf.

Since, the range of data = Maximum value of observation - minimum value of observation,

= 45 - 26

= 19

Thus, Option C is correct.

The answer is 32.5

19

Step-by-step explanation:

Stem and Leaf Plots

It is a special table where each data value is split into a stem (the first digit or digits) and a leaf (usually the last digit).

So, in the given plot

the first stem 2 has leafs = 6,7,7

So, the numbers will be 26,27,27

So, in this way we can write the stem leaf plot data in normal data form

Now to calculate range

Range = Highest number - lowest number

The first stem 2 and its first leaf 6 . So,number = 26 is the lowest number

The third stem 4 and its last leaf 5 . So, number = 45 is the highest number

Thus Range = 45-26=19

Hence the range of data  is 19

Mean-17

Median-3

Mode-3

Range-47

Greatest Value-47

Least Value-0

Step-by-step explanation:

Mean= Add every number up then divide by how many numbers there are

Median= It has an even number in total when ordered from least to greatest. So take the two middle numbers together and divide them by 2.

Mode= The number that occurs more often

Range= The difference between the highest and the lowest number.

47-0=47

Greatest and lowest value= the highest and lowest number in a data set.

The median is 31.5

The mode is 39

The range is 31

Step-by-step explanation:

The median is the middle number of arranged data from small to big in a set of data

The mode is the most repeated number in a set of data

The range is the difference between the greatest and the smallest numbers in a set of data

The data from stem-and-leaf plot are

11, 11, 12, 22, 22, 25, 27, 27, 36, 39, 39, 39, 39, 40, 42, 42

∵ There are 16 data

- There is no one middle number because the number of the

    data is even, so the median will be the average of the

     two middle numbers

∵ 16 ÷ 2 = 8

∴ The middle numbers are the 8th and the 9th numbers because

   there are 7 numbers before them and seven numbers after them

∵ The 8th number = 27

∵ The 9th number = 36

∴ The median =

∴ The median = 31.5

∵ The mode is the most repeated number

∵ 39 is repeated 5 times and no other number repeated more

   than 5 times

∴ The mode is 39

∵ The range = Greatest number - Smallest number

∵ The greatest number is 42

∵ The smallest number is 11

∴ The range = 42 - 11

∴ The range = 31
