The three uniformity coefficients (Cu, U and A) were calculated for 775 uniformity tests that had been conducted at Swift Current from 1954 to 1959. A computer program was developed for these calculations which was of particular value for calculating the coefficient A because of the complexity of the procedure involved in ranking the numbers and making the required calculations. A computer program was then used to calculate the various components in correlation analysis. In an attempt to obtain coefficients of more nearly like values in each group, the data were analyzed on the basis of sprinkler spacing. This was partially successful so more divisions were made by grouping on the basis of wind speeds and sprinkler pressures. However, no improvement was achieved, partly because the number of observations in each group became too small, so the discussion will be limited to the grouping ac cording to sprinkler spacing.
