Which type of data is best represented using a line plot?

a. data that changes over time

b. data that is spread out over a large range of numbers frequency

c. data that can be plotted under categorical headings frequency

d. data that can be plotted on a number line

Answer with explanation:

In a Line plot, we draw a number line, mark distinct variate on it.In front of each variate, we mark points to represent total frequency of each variate.

For, example :

A.  When data changes over time, Suppose at time ,A,value of that thing was 3. at B,it was 5, at time C , it was 7,Mark , A, B and C,.. on number line and put three dots in front of A, 5 dots in front of B, 7 dots in front of C,But Bar graph,or Histogram is best suited for this Model .

B.Suppose, Data set is not discrete

  Data          Frequency

    1                    3

     2                  4

    3                    6

    4                    8

    5                    4

    6                    12

Make number line. Mark Data which are numbers, on the number line, and Represent frequency over each variate either by point or any other sign.

⇒Most Appropriate for Line Plot.

C:

Categorical Heading          Frequency

  A                                                4

AB                                                 5

ABC                                              8

A CD                                            12

Draw a Number line,Instead of marking numbers, mark heading at equal Distances and represent frequency through any Sign, above each Categorical Data.

⇒Appropriate for Line Plot but bar graph most suited.

D:

 You need frequency , along data .So, alone Data is not sufficient for , Line plot.

⇒≡Option B and Option C, are best suited for line Plot.

Going with→ Option B

⇒Data that  is spread out over a large range of numbers frequency.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
