The relative frequencies are as follows: RF (Head) = 24 / 50 RF (Tail) = 26 / 50 When the number of repetitions of the experiment is increased, the relative frequency seems to be approaching a fixed value. We can use relative frequency to estimate probability. Created for teachers, by teachers! Quartiles Tom continued in this way, recording his combined results after every $${10}$$ trials and plotting them on the graph below: We can see from the graph that relative frequency gets better (ie closer to the true probability) as the number of trials increases. Tom took a sweet from the bag, noted its colour and then replaced it. Experimental Relative Frequency describes how you can get a more accurate result in surveys of events if you carry out a large number of trials or survey a large number of people. Ready-to-use mathematics resources for Key Stage 3, Key Stage 4 and GCSE maths classes. A few multiple choice questions lead into a students investigation and a differentiated main task.
