We are given the following data set for the number of skips every time Jake skipped a stone onto a pond:
3, 2, 1, 3, 2, 5, 4, 1, 3, 3, 4, 1, 5, 4, 2
It is a good idea to arrange the data set into ascending order just to be more clear about it:
1, 1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5
To find the most common number of skips, Jake should use a measure called mode which tells us about the value that appears most often, which in this case is 3.
Both are
indicators of the chemical composition of silicate minerals, magmas and rocks.
Mafic is
used for silicate minerals, magmas and rocks that are composed of heavier
elements, like magnesium, iron, calcium and sodium. They are dark and have high
specific gravities.
<span>Opposite to
the this, felsic silicate minerals, magmas and rocks in their composition have
less from these heavy elements. They are composed from silicon, oxygen,
aluminium and potassium, are light in color and have lower specific gravities.</span>
