Game: THE FROG FLIES
Aim: Help the frog catch the flies
Method:
Use keyboard arrow keys or tap your tablet/mobile to control the frog and catch the flies. Avoid the birds! Answer the math questions to win additional points.
Scoring is based on speed, flies caught and the number of correct answers.
7th 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 The frog flies math game you will be practicing the topic "Polarity, strength of correlation" from 7th 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.
Learn or revise math with our fun interactive game THE FROG FLIES! You are a happy hungry frog in the middle of the jungle in the middle of the night. Catch the flies for your supper (and practice math just for fun).
You can play the game on tablet/mobile or desktop computer. On handheld devices you move the frog by tapping where you want it to move to. On a computer, use the arrow keys on your keyboard to move.
Sometimes a big bird swoops through the forest catching unwary amphibians so stay alert and get out of the way of its beak!
Scoring is based on flies caught, questions answered and number of deaths by bird. Your final score is your total points minus your time in seconds.
The highest scores for each topic can be saved and seen by clicking on the star button, so get learning and get your frog's name up in lights!
