Experimental Design

Experimental Design Sasmita Mishra

What is experimental design Experimental designs are those where the researcher tests the hypotheses of causal relationship between variables. To establish that variable X causes variable Y, all three of the following conditions should be met:  Both X & Y should covary  X should precede Y  No other factor should cause the change in the Y.
