Grouped frequency tables
Data in frequency tables can be discrete or continuous. Discrete data consists of single values, often whole numbers, and is how most data is initially gathered. If there are many data points to process, it becomes useful to group that data into a set of classes of continuous data. Continuous data can be represented in a "Grouped frequency table". Each class covers the data points within a certain range, and the classes together cover the entire range of all the data points. In grouped frequency tables, it is important that the classes cover the entire range of the given data while not overlapping.
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, median or range of the original discrete data points becomes impossible.
In this topic you are asked to compare each grouped frequency table to the raw data that it should represent. Many of the tables have deliberate mistakes that you must identify. You can do so by counting up the data points for each class and comparing them to the given frequencies.
In the first question, the raw discrete data points are:
10, 8, 25, 18, 15, 22, 5 ,9
The grouped frequency table splits the data into classes: 1-10, 11-20, 21-30.
The frequency for the 1-10 class is given as 4. We can look through the data points and confirm that there are indeed 4 values within this range: 10, 8, 5 and 9. So that frequency is correct. Checking the 2 other classes shows us that the table does indeed accurately represent the data, so the answer in this case is "yes, the table does match the data".
With our Mix and match math game you will be practicing the topic "Grouped frequency tables" from 7th grade / Statistics / Continuous data / Continuous data. The math in this game consists of 16 questions that ask you to in each instance decide whether the grouped frequency table matches the raw data.
In this game we are in a room with lots of toys - and the room needs clearing up - you need to put the play blocks back in the right boxes to tidy the room and win the game...but which is the right box for each block? Well, you can work that out by comparing the question on the block with the math answer on each of the boxes - you should drag the question block into the box whose math answer matches the picture question.
You can listen to the spoken math answer by clicking on the individual boxes. There are 5 blocks to clear up - but if you put them in the wrong boxes, there will be more... Anyway, tidy is good and practicing math is better so start now and see how you get on...
This game reinforces the math you learned or revised in the lesson by asking you to match each question to the correct answer. If you are older you may not like the childish reference to toys, but don't worry - there are other games to play, and who knows - you might like a trip down memory lane?

'Grouped frequency tables' for 7th grade
There are 5 blocks that need putting away to tidy the play room. Drag (they are heavy...) the blocks to the correct boxes.
- Click on "PLAY" on the settings page to start the game
- You see the first question block and 3 boxes to put it into
- On each box is a possible math answer to the question
- Click on any answer box to hear the spoken audio for that answer
- Drag the question block to the answer box where it belongs
- If you are correct, the block will stay in the box, the ball will roll and the teddy bear will do a little jump
- If you are wrong, a wrong sound will play and the question block will jump back to where it was, and you can try again
- Clear all 5 question blocks to complete the game
