HC Deb 14 May 1982 vol 23 c342W
Mr. Ernie Ross

asked the Secretary of State for Employment if he will evaluate the product-moment correlation coefficient and its level of significance between (a) the average annual number of males out of work for one year or more and (b) the incidence of industrial accidents in premises covered by the Factories Act per 100,000 at risk for the latest 10-year period for which figures are available.

Mr. Waddington

The result of testing the product-moment correlation coefficient for the data described over the latest 10-year period shows that the supposed correlation between the two series is not significantly different from zero even at the 10 per cent. level of significance.
