III only

Answer :

lucic

I, II, and III

Step-by-step explanation:

From dot plots, the steps used are;

  • ordering data from smallest to largest
  • Finding median
  • Finding median of both lower and upper half of the data
  • Finding the difference between the medians of both lower and upper half of the data.

From the histogram steps involved are

  • From the cumulative frequency histogram polygon, find the upper quartile which is 3/4* highest column value
  • locate value in step on in the c.f column on the y-axis
  • after locating the value on the c.f column, draw a horizontal line from that point to hit the polygon and draw a vertical line all the way down to hit x-axis, this is the upper quartile (Q3) value
  • Repeat the procedure for lower quartile using 1/4*the highest column value.
  • The range is obtained by finding the difference between upper quartile, Q3 and lower quartile Q1

From the box plot, the steps for finding interquartile range are;

  • Find Q1 which is represented  on a box plot by the left-hand edge of the box.(where the whisker stops)
  • Find Q3 which is represented on a box plot by the right hand edge of the box
  • Find the difference ,Q3-Q1, to get the interquartile range
