Hiya, I was just wandering what a stem and leaf diagram is and also how to work out the mean of a frequency table because I have not put enough information in my notes.
Thanks
Hi Rosie,
Have a look here for stem and leaf:
http://www.bbc.co.uk/schools/gcsebitesize/maths/data/representingdata2rev4.shtml
Mean = sum of every value divided by the total number of pieces of data.
If the data has been summarised in a frequency table, you need to remember to include each value the correct number of times.
