Math 11 Essentials
Unit 2 Review
A player’s mean average may not have that great of an effect on their standing. Take
Mario Lemieux for example: he has the highest mean average number of points per game,
but he’s ninth in total points.
g) Those on the top seem to have a higher average number of games plated, but there are also
some near the bottom who played some of the higher number of games e.g. Ray Bourque.
h) For both cases, there are exceptions to the rule. For question “f”, Wayne Gretzky has the 2nd
best mean-per-game average, but Howe and Messier only have mediocre mean averages, yet
they’re still near the top. For question “g”, there is a very disconnected relationship with how
many games played and the player’s standing in the top ten list.
e) 47, 000,000
f) Vincent Can Gogh’s portrait of Dr. Gachet sold for the most amount of money, at
$112,500,000. Out of all the paintings of Van Gogh’s on the top ten list, collectively, his works
sold for $ 183,500,000. The painter’s word that sold for the most collectively was Picasso, with
total sales at $351,500,000.
g) There appears to be no solid relationship between the year that the painting was sold, and the
price it was sold at, save for the year 1990 –which is when the two most expensive paintings
were sold.
c) The most affected measure of central tendency is the mean.
4. a) Both the grade that Ms. Wise and Mark presented were forms of central tendency and
expressions of averages.
b)My opinion is that neither the mode (which Ms. Wise used) nor the median (which Mark used)
are the best expressions of Mark’s biology average. Rather, the mean average would give the
best understanding of Mark’s grades.
b)
c)
11 a)
b) Although the circle graphs make it appear that Nunavut has twice as many young people as
British Columbia, the amount of a circle that an age category occupies is only relative to the total
population of that province or territory. So it is true that Nunavut has more people aged 0 – 14
proportionately, than British Columbia.
c)The population of people aged 65 and older may be significantly lower in the Northern
provinces than in either Manitoba or British Columbia because they have retired and desire to
live in a warmer climate, or maybe the elderly can’t receive the care they need in the more
isolated and lower population provinces/territories.
