The statistical values such as mean, Median and mode gives measure of centre of a data, while the midrange gives information about the spread. Hence, the statistical measures are :
- <em>Mean</em><em> </em><em>=</em><em> </em><em>44.36</em>
- <em>Median</em><em> </em><em>=</em><em> </em><em>38</em>
- <em>Mode</em><em> </em><em>=</em><em> </em><em>1, 3, 16, 24, 26, 38, 49, 69, 80, 89, 93</em>
- <em>Midrange</em><em> </em><em>=</em><em> </em><em>46</em>
<u>Given the data</u> :
- <em>1, 3, 16, 24, 26, 38, 49, 69, 80, 89, 93</em>
Mean = [Σx ÷ n]
Mean = (24+26+89+16+38+69+93+3+1+80+49) / 11
Mean = (488 ÷ 11) = 44.36
<u>The median</u> :
Median = 0.5(11 + 1) = 6th term
Median = 38
<u>The Mode</u> :
The most frequently occurring value in a distribution ; since each the value occur just one, then there is no single mode value.
<u>The midrange</u> :
Midrange = (93 - 1) / 2
Midrange = 92/2 = 46
Therefore, the midrange is the value of the range divided by 2.
