Game: ROCK FALL
Aim: Smash all the falling rocks
Method:
Click / tap on each falling rock. Answer the question in the box as quickly as you can.
There are only 4 questions in this game so it is quite short... if you can get those rocks!
Your final score is based on number of questions answered right / wrong, and the time taken.
8th grade / Statistics / Continuous data / Continuous grouped data / Grouped frequency table: modal group, range
Continuous data can be represented in a "Grouped frequency table" where each class (group) covers the data points within a certain range, and the classes together cover the entire range of the data.
The benefit of grouped frequency tables becomes clear when there are so many raw data points that discrete values would become difficult to process. A limitation of continuous data is that individual data points are lost so that exact calculations of the mode or range of the original discrete data points becomes impossible. Instead techniques have been developed to approximate these values for continuous data.
Instead of a mode (the most frequent individual value in a data set), we can find the "modal group" which is the class of data that has the highest frequency. So if we have a grouped frequency table with classes 1-20, 21-40 and 41-60 that have frequencies of 12, 7 and 5 respectively, then the modal group is 1-20 because it has the highest frequency of 12.
Instead of an absolute value for the range of a data set, we can find the "largest range". This is the difference between the largest possible value in the biggest class and the smallest value in the smallest class. So if our grouped frequency table has classes 21-40, 41-60 and 61-80, then the largest range is 80 minus 21 which is 59.
In this topic you are asked to find either the modal group or the largest range for a series of grouped frequency tables. There are 8 question/answer pairs in the lessons, and an additional 8 question/answer pairs in all the games and tests.
With our Rock fall math game you will be practicing the topic "Grouped frequency table: modal group, range" from 8th grade / Statistics / Continuous data / Continuous data. The math in this game consists of 16 questions that ask you to identify the modal group or largest range for each grouped frequency table.
ROCK FALL is based on the road traffic warning sign for falling rocks - a sign that seems a bit less useful than somebody getting up there on that cliff and actually doing something about it... Anyway, the rocks are falling and it is your job to stop them hitting the road below, or at least stopping them hitting the road below too many times and breaking it. Smash the rocks by clicking or tapping on them (not so easy in real life of course) - they will turn into snowflakes and float gently down into nothing.
There are 4 rocks to stop and not much time to do it (if you want to get a good score and get on the leaderboard). This game is fun and fast and requires good reflexes and a good strategy. Plan to break the smaller rocks first if you want a good score because the rocks fall faster as the game progresses. It also helps to decide where on their path you plan to click / tap the rocks.
