You have not completed the Tally column
correctly. For each score in the list of raw
data, you should find the class for that
score in the tally table and make one mark
in the tally column next to it. Remember
that when you get to 5 tally marks, you
should use a five bar gate.
@Feedback 0,?,?,?,?,?,?,?,?
Wrong. For each score in the list of raw

score in the tally table and make one mark

@Answer 8,4,5,7,8,7,3,3,3
@Feedback E1,?,?,?,?,?,?,?,?
That isnÆt right. You must add up all
the tally marks for each class of data
to find the frequency.
@Feedback 0,?,?,?,?,?,?,?,?
Wrong. You must add up all the
tally marks for each class of data
to find the frequency.
@feedback 8
Well done. All the tally marks are
added up to give the frequency
for each class of data.

Now take the class with the highest frequency
and complete the following.
@at ,+2
@InputWidth  34
Upper bound = #[N] Lower bound = #[N]
@Answer 4,159.4,154.5
@Feedback E2,?,?
Partly right. The class with the highest
frequency is 155-159. Because height
is a continuous measure, we write the
upper bound as #b159.4# and the lower
bound as #b154.5#
@Feedback E1,159,154
Partly right. The class with the highest
frequency is 155-159. Because height
is a continuous measure, we write the
upper bound as 159.4 and the lower
bound as 154.5

@Feedback 4
Yes, well done. The class with the highest

continuous measure, we write the upper
bound as 159.4 and the lower bound as 154.5
