Question

Given below are the steps to be followed to draw a line plot for a data set. Which step is incorrect?
Step 1: Arrange the given fractions in ascending order.
Step 2: Find the distinct values or fractions and the number of times each value or fraction appears in the data set.
Step 3: Plot the frequency of each data set or value for all the fractions.

• A. Step 2 is incorrect.
  
• B. All steps are correct.
  
• C. Step 3 is incorrect.
  
• D. All steps are incorrect.
  

Answer 1

The correct option is B All steps are correct.


Let’s represent the following data table using a line plot.

Restaurant	Restaurant 1	Restaurant 2	Restaurant 3	Restaurant 4	Restaurant 5	Restaurant 1 Restaurant 6
Fraction of vegetarian customers	$\frac{1}{2}$	$\frac{1}{2}$	$\frac{3}{4}$	$\frac{1}{4}$	$\frac{1}{4}$	$\frac{1}{2}$

Step 1: Arrange the given fractions in ascending order.
$\frac{1}{4},\frac{1}{4},\frac{1}{2},\frac{1}{2},\frac{3}{4}$
Step 2: Find the distinct values or fractions and the number of times each value or fraction appears in the data set.
$\frac{1}{4}$ appears twice, $\frac{1}{2}$ appears thrice, and $\frac{3}{4}$ appears once.
Step 3: Plot the frequency of each data set or value for all the fractions.
Hence, all the given steps are correct.
