Game: DUCK SHOOT
Aim: Shoot as many ducks as you can
Method:
Use the catapult to shoot balls at the rows of ducks crossing the screen. Answer questions to win extra points.
Your final score is based on ducks hit or missed and the number of questions answered correctly.
8th grade / Statistics / Two variables / Scatter graphs / Polarity, strength of correlation
Scatter graphs use dots or diagonal crosses to represent values that correlate the relationship between two variables. The scatter graph will indicate the degree to which the two variables are correlated (linked or related).
For instance, a scatter graph plotting altitude (x-axis) against Oxygen concentration (y-axis) will indicate a strong correlation between these two variables because Oxygen concentration reduces with altitude (the reason climbers can suffer from altitude sickness). On the other hand, a scatter graph plotting eye colour against exam results will show no correlation because these two variables have no causal relationship.
The polarity of a correlation can be characterised as "positive" or "negative". This indicates whether an imaginary straight line drawn through the points (a line of best fit) rises to the right (positive - as the x-axis variable increases, so does the variable on the y-axis) or falls to the right (negative - as the x-axis value increases, the y-axis variable decreases). So, thinking about our example of altitude plotted against Oxygen concentration, we will see a negative correlation because the concentration decreases as the altitude increases. A positive correlation would be seen if we plotted a child's age against shoe size: as their age increases, so does their shoe size.
The strength of a correlation can be characterised as "strong" or "weak". A strong correlation will be indicated on a scatter graph by points that closely follow a line of best fit. A weak correlation will show points that are more loosely concentrated around a line of best fit.
In this topic you are asked to decide which of the descriptions provided best describe the correlation between the variables plotted on the x and y axes. The possible options are:
With our Duck shoot math game you will be practicing the topic "Polarity, strength of correlation" from 8th grade / Statistics / Two variables / Two variables. The math in this game consists of 16 questions that ask you to identify the polarity and strength of any linear correlation for each of the given scatter graphs.
DUCK SHOOT is a fun game to learn math where you attempt to knock over all the fairground ducks in each level. In the first level there are only 6 ducks but by level 10 there are 24 fast moving "quackers quacking"...
After each level, win an additional 20 points by correctly answering a math question from your selected topic. There is no timer in this game: take as long as you like to answer the math questions correctly for a best score to get you on the DUCK SHOOT leaderboard.
