For the past weeks in research we’ve studied about the Measures of Central
Tendency which is the mean, median and the mode and how
to get those in an
“Ungrouped frequency” distribution. After that we studied
getting the measures of
central tendency in a grouped frequency distribution . We
first tackled the way to get
the mode in a grouped frequency distribution which is the
easiest of them all. All you
have to do is to find the “score” with the highest
frequency just like the one that we
used to do in the ungrouped frequency distribution then you subtract the low score
from the high score and divide it by two. After
discussing the process to get the
mode from a grouped frequency distribution I was hoping
that we’d discuss the way
to get the median next but instead our teacher discussed
the way to get the mean
first. We all asked him why he’d discuss getting the mean
first and he said that it was
because it’s easier to get the mean than the median in a
grouped frequency
distribution . and the formula in getting the mean in a
grouped frequency distribution
was a bit complicated. After discussing the process in
getting the mean in a grouped
frequency distribution
our teacher discuss the process in getting the median of a
grouped frequency distribution. When our teacher started discussing I saw everyone
with a blank face.
It really was a bit complicated I can hear everyone saying : “I don’t
get it” , “ what’s that again ? “ I admit I don’t get it at first either but I
soon got it as I
asked some of my classmates who gets it . Even though our lessons are getting
tougher I must not give up because I know that all these
are part of learning. Thank
you for teaching us.
