Investigation of Film Lengths The title of my investigation is 'The Average Length of a Sample of 52 Randomly Selected Films'. As you can interpret from this title, I am going to investigate into the length of a set of randomly selected feature length films. I have chosen to investigate into this topic because I am a Film Studies student and am required by this subject to produce a feature length film as part of a coursework assignment.

In contrast, is there a certain length of film that after the audience has finished watching, they are bored because the film has run on for too long? In short, my aim for this investigation is to find the average length of feature films and so enable me to correctly decide the length of my Film Studies coursework film so that the audience leaves happy after viewing it. To determine a population for my course-work, I am going to use the HMV superstore Internet site to search for my sample of films. This film site is split up into categories corresponding to letters of the alphabet; therefore there are a total of 26 categories as there is 26 letters of the alphabet. Each category contains roughly 500 films giving a total population of 130,00 films. Obviously this population is far too vast, so I what I propose to do is to number each film in a category and then the random number generator function on my calculator to give two random numbers. I then match up the numbers with the corresponding films, and get two films for each category, complete with total running time and year of release. I will therefore end up with a sample of 52 films, fulfilling the criteria of a sample
