Mr. and Mrs. Smith want to find out
which city has the largest shopping centre that can satisfy all four of their
children’s need to walk, shop, watch, eat and play! They went online and found
information on the following 4 shopping centres in the Lower Mainland:
|
Shopping Centre |
Metrotown |
|
Oakridge
Mall |
Pacific
Centre |
|
Number of Stores |
387 |
240 |
140 |
150 |
1)
Rank the four shopping centres from the
one having the least number of stores to the one with the most number of
stores.
2)
The “RANGE” of a set of data is the
difference between the largest and smallest number.
What is the
range of the above numbers?
3)
The “MEAN” of a set of data is the
average of the set of data values.
Mean
= sum of all the data values / the number of data values
What is the
mean of the number of stores of the four shopping centres listed above?
4)
The “MEDIAN” of a set of data is the
data value in the middle of the set when the values are placed from smallest to
largest. If there is no middle number, the median is calculated by taking the
mean of the middle two numbers.
Find the
median of the number of stores according to the values in the above table.
5)
The “MODE” of a set of data is the data
value that appears the most often.
Does the above
set of data values have a mode?
If so, what is
the mode?
6)
If Oakridge Mall was renovated and 10
more stores were added, will the new set of data values have a mode?
If so, what is
the mode?
7)
Based on the above analysis, which
shopping centre should Mr. and Mrs. Smith take their children to? Why?
Suddenly, there was a strange expression on Mr. and Mrs. Smith’s faces,
like they had a perfect solution. At first they mouthed a word to each other
and then nodded in agreement, like they always did. “Metrotown, kids we’re
going to Metrotown!” proclaimed Mr. and Mrs. Smith. The Smith’s household erupted with
satisfaction and ‘high-fives’ all around. They caught one of the many direct
buses to Metrotown and rode out to their destiny.
