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.
7th grade / Statistics / Discrete data / Frequency tables / Mean mode median range
Frequency tables are a way of laying out data to show the number of items there are in different categories. From frequency tables you can see what are the most and least frequent categories, and easily calculate mean, mode and range for a data set. They are also used as a source to generate more graphical representations such as bar charts, pie charts, etc.
Frequency tables make it easy to find the mode, median and range for a data set. The mean takes a little more work.
The mode is the most frequent value in a data set. To find the mode from a frequency table, find the item or category with the highest frequency.
The median is the middle value in an ordered data set. To find the position of the median value in a frequency table, add up all the frequencies in all the categories, add one more and then divide by two. This will identify the position of the median value of the data set. If the result is a decimal, the position of the median value is halfway between two frequencies.
The range is the spread of values in a data set. To find the range of data from a frequency table, take away the smallest value from the largest value.
The mean is the average value of a data set. To find the mean from a frequency table, do the following. Multiply each category by its frequency. Add these values to get the total value from all the categories. Add all the frequencies together to get the total frequencies. Now divide the total value by the total frequencies to get the mean.
In this topic you are asked to derive the mean, mode, median or range for a series of frequency tables.
There are 8 question/answer pairs in the lessons for this topic, 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 "Mean mode median range" from 7th grade / Statistics / Discrete data / Discrete data. The math in this game consists of 16 questions that ask you to calculate the mean, mode, median or range for the given frequency tables to 2 d.p..
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.
