Maths

In maths today, we have been learning how to construct graphs and then using the data to find the range, median and mean. Here are the results from our enquiry:



The mode is the number or thing that occurs most frequently in a piece of data, can you tell us the mode of our data?
In order to find the range, we took the highest piece of data (58) and the lowest (0) and found the difference which was 58.
To calculate the median we needed to rearrange the data into order from the lowest to the highest and then find the middle - our data was made up of an even amount of data so we were left with two middle numbers - in this situation we needed to add the two middle numbers together and then divide the answer by two - can you find the median of our data?
Finally, to calculate the mean, you need to add all of the data together in the tally chart (58, 7, 6, 4, 3, 2 ,1 0) and then divide the answer by the number of pieces of data (8) - can you work out the mean for our data?
Please comment with your answers,
