It just dawned on me today that I could add up all the interruption coefficients accrued by each political party and work out an average I.C. - a 'super-average' - for that party across the BBC's output throughout July.
Now, a strong health warning is necessary here:
With all statistics, the larger the sample the better the result. If you ask one person in the street his opinion on something & then generalise from that you are, obviously, making a biiiiiiggg mistake (as Robert Peston might say). Similarly, if the average is based on just one interview (as in the BNP and Plaid Cymru examples featured below) or two (as in the case of UKIP) or even four (as with the Greens) or six (as with the SNP), the result is not to be taken toooo seriously - though with each increase the result becomes stronger. With a large sample (as for the Liberal Democrats), a larger sample (as for the Conservatives) or with a very large sample (as for the Labour Party), the results become much more convincing and revealing. I believe that the figures below are already of some importance in demonstrating the BBC's bias towards the Labour Party and (even more so) the Liberal Democrats and against the Conservative Party.
So, with those riders firmly borne in mind, here are the 'super-average' I.C.s for the BBC as a whole for July 2009:
Plaid Cymru - 2.3
UKIP - 1.7
BNP - 1.1
SNP - 1.0
Conservatives - 0.9
Labour - 0.5
Liberal Democrats - 0.3
Greens - 0.1
With each passing month these 'super-statistics' will become ever more telling. If such a trend is confirmed the BBC will be proved to be biased. Conversely, of course, if they are not it won't. Watch and see!
