Help please!
A group of 10 students participated in a quiz competition. Their scores are shown below:

4, 4, 3, 4, 3, 12, 4, 3, 2, 3

Part A: Would a dot plot, a histogram, or a box plot best represent the data shown above if the purpose of the graph is to highlight the frequency of each individual score? Explain your answer.

Part B: Provide a step-by-step description of how you would create the graph named in Part A. OR include a picture of a graph you create to represent the data.

Respuesta :

Answer:

This is a relatively small data and if the purpose of the graph is to show the frequencies only, the most suitable graph would be a dot plot.

List the data in the ascending order:

2, 3, 3, 3, 3, 4, 4, 4, 4, 12

The scale of the graph is 2 to 12.

Draw a number line 2 - 12.

Place the number of dots above each number.

The graph will look like this:

1 dot   4 dots 4 dots                                                                                       1 dot

-2--------3--------4--------5--------6---------7---------8---------9--------10--------11---------12

I know i copied and pasted but i just wanted to help more people.

Have a nice day :)

Answer:

Part A

A dot plot would best represent the data shown because dot plots are suitable for situations where there are only a few options on the horizontal axis and not too many occurrences of each grouping.

Part B

See attached for the completed dot plot

To create the dot plot:

  • Draw a horizontal line with arrows at each end.
  • Consider the range of data and divide the line into equal portions, ensuring the first and last ticks are the smallest and largest data values.  Add numbers for each tick.
  • Count the number of data values for each number on the line and draw that many dots above it (e.g. if you have one data value of 2, draw one dot above the number 2 on the number line).
  • Finally, add a title describing what the numbers on the number line represent.
