Select the correct answer.<br> Which statement is true about a dot plot?
Lemur [1.5K]

Answer:

The statement that is true about dot plot is:

A dot plot shows the frequency of the individual values of any given data set

Step-by-step explanation:

A dot plot also known as a dot chart or a strip plot is just a display of the data depending upon the frequency of the values.

The dot plot is somewhat like the histogram but the difference is:

A histogram shows the frequency of an interval of values of any given data set.

     for example:

  we may make a histogram for the weight of students of a class.

  since we may divide the weight of the students into some interval.

whereas the dot plot gives the frequency of the individual data points or discrete data points.

      for example:

     we may plot a dot plot for rolling a number cube 20 times.

Hence, the correct statement is:

A dot plot shows the frequency of the individual values or of any given data set.
