<span>The first equation is x + y = 27 For the second equation, there are twice as many girls (y) as boys (x), so you write: y = 2x Now you have a system of equations: x + y = 27 y = 2x</span>

Effectus [21]

The mean, median, standard deviation, and interquartile range for each data set is given below.

<h3>What is the definition of Interquartile Range (IQR)?</h3>

When arranged from lowest to highest, the IQR represents the central 50% of values.

Find the median (middle value) of the lower and higher half of the data to get the interquartile range (IQR).

These are the quartile 1 (Q1) and quartile 3 (Q3) values (Q3). The difference between Q3 and Q1 is the IQR.

<h3>What are the measures of central tendency for Manuels Data?</h3>

Using the statistical tool, the following were arrived at:

  • Standard Deviation = 3.13961
  • Mean = 8
  • Median = 8
  • IQR = Q3-Q1 = 10 - 6 = 4

<h3>What are the measures of central tendency for Grethcen's Data?</h3>

Using the statistical tool, the following were arrived at:

  • Standard Deviation = 4.68737.
  • Mean = 9.6
  • Median = 9
  • IQR = IQR = Q3-Q1 = 12 - 7 = 5.

See the respective Histograms attached.
