### GCSE Module 1 Notes

More links etc will appear here soon, any thing I've missed that you want let me know

What you need to be able to do (this is for Higher)

- identify the advantages and disadvantages of each type of average and know which one to use in different situations
- calculate the mode and median from a frequency table
- calculate the mean from a frequency table
- identify the modal group
- calculate and estimate the mean from a grouped table
- Calculate the median and interquartile range of grouped data
- draw frequency polygons for discrete and continuous data
- draw histograms for continuous data with equal intervals
*draw and read histograms where the bars are of unequal width**find the median, quartiles and interquartile range from a histogram**calculate a moving average and use it to predict future trends*- conduct surveys and ask good questions to collect reliable and valid data
- interpret some of the more common social statistics in daily use
- understand different methods of sampling
- draw a line graph to show trends in data
- draw and read information from an ordered stem-and-leaf diagram
- draw, interpret and use scatter diagrams
*find a measure of dispersion (the interquartile range) and a measure of location (the median) using a graph**draw and read box plots*- calculate standard deviation for a set of data – not in exam but useful for coursework task

- calculate experimental probabilities
- estimate probabilities from experiments
- use different methods to estimate probabilities
- recognise mutually exclusive, complementary and exhaustive events
- predict the likely number of successful events given the number of trials and the probability of any one event
- read a two-way table and use them to work out probabilities and interpret data
- work out the probability of two events such as P(event A) or P(event B)
- work out the probability of two events occurring at the same time
*use sample space diagrams and tree diagrams to work out the probability of combined events**use the connectors ‘and’ and ‘or’ to find the probability of combined events**work out the probability of combined events when the probabilities change after each event*
