In the analysis of variance, the sum of the squared deviations between each block sample mean and the grand mean, multiplied by the number of observations made for each block, multiplied by the number of observations per cell (which may well equal 1) equals the blocks mean square.
  Indicate whether the statement is true or false

Q. 2

The completely randomized design is an experimental plan that divides all available experimental units into blocks of fairly homogeneous units - each block containing as many units as there are treatments or some multiple of that number - and then randomly matches each treatment with one or more units within each block.
  Indicate whether the statement is true or false

Q. 3

In employing the randomized block design, the primary interest lies in reducing sum of squares for blocks (SSB).
  Indicate whether the statement is true or false

Q. 4

Blocking is a procedure that lets extraneous factors operate during an experiment but assures - by virtue of the random selection of experimental units and their subsequent random assignment to experimental and control groups - that each treatment has an equal chance to be enhanced or handicapped by these factors.
  Indicate whether the statement is true or false

Q. 5

In a two-way ANOVA, there are 4 levels for factor A, 3 levels for factor B, and two observations within each of the 12 factor combinations. The number of treatments in this experiment will be 12.
  Indicate whether the statement is true or false

Q. 6

A randomized block experiment having five treatments and four blocks produced the following values: Total SS = 1500, SST = 275, SSE = 153 . The value of MSB must be 268.
  Indicate whether the statement is true or false

Q. 7

The randomized block design is a two-way classification design.
  Indicate whether the statement is true or false
