In this paper, a study of second order slope rotatable designs under intra-class correlation error structure using two suitably chosen dissimilar incomplete block designs like balanced incomplete block designs and symmetrical unequal block arrangements with two unequal block sizes are suggested. Further, we study the variance of the estimated slopes for different values of the intra-class correlation coefficient (ρ) and the distance from the centre (d) for v factors are suggested. Some illustrative examples are also suggested.

In this paper, a study on second order rotatable designs under tri-diagonal correlated structure of errors using a pair of balanced incomplete block designs is suggested. Further, the variance function of the estimated response for different values of tri-diagonal correlated coefficient and distance from centre  for  ( - factors) are studied.

A method for constructing second-order rotatable desians in k dimensions from second-order rotatable designs in k - l dimensions (1 ⩽ l ⩽ k -1) is proposed. The method makes use of balanced incomplete block designs. The method always works and, further, the experiments performed according to the ( k - l)-dimensional design need not be discarded.
