You may find it helpful to start with the main frequency table lesson for a summary of what to expect, or use the step by step guides below for further detail on individual topics. Other lessons in this series include: Frequency table Mean from a frequency table Grouped frequency table ...
A frequency polygon is a graph that shows the frequencies of grouped data. The points are plotted using the midpoints of the class intervals against the frequencies and then the points are joined up with straight lines. For example, Here is the frequency table showing the results of a Histor...

so know exactly what I am looking for in terms of the teaching gift - and Francesca certainly has this gift. Being extremely knowledgeable does not always mean being able to teach. Not only is Francesca of superior intelligence, but she is really able to relate to my daughter. The benefits...
When quit, the output must display the mean of the numbers. Write a programme so that a user enters a list of numbers, one at a time, until the user enters 'E' to quit. With each input, the output should be the median of the numbers. Write a programme to get the sum, product...
records the colour and replaces the ball in the bag.Amy does this 60 times and calculates the relative frequency of red after every 10 goes.Her results are shown on the graph.(a)Use the graph to calculate the number of times Amy picked a red ball in the first 10goes...Answer ......
distribution find the median for a discrete frequency distribution or stem-and-leaf diagram choose an appropriate measure according to the nature of the data to be the ‘average’ compare two distributions by comparing the range and a suitable measure of average such as the mean or median View ...
It makes use of the imported statistics module, which includes mean, median and mode methods. Error handling is incorporated to prevent the user from entering any non-integers and to stop the program from crashing if the mode can't be calculated for the given set o...
