Question

Which data set has the widest spread

Answer 1

Answer:

Data set C.

Step-by-step explanation:

We have been given four data sets. We are asked to choose the data set with widest spread.

We know that the spread of a data set can be measured by range.

$\text{Range}=\text{Upper data point}-\text{Lower data point}$

Let us find range of each data set.

A. $\text{Range of data set A}=2-1$

$\text{Range of data set A}=1$

B. $\text{Range of data set B}=4-2$

$\text{Range of data set B}=2$

C. $\text{Range of data set C}=5-1$

$\text{Range of data set C}=4$

D. $\text{Range of data set D}=5-3$

$\text{Range of data set D}=2$

Since the range of data set C is greatest, so data set C has the widest spread.

Answer 2

Spread = highest value - lowest.
Its data set C  Spread is 5 - 1 = 4
