Type 95 Heavy Tank into production. It proved to be a complicated design with poor mobility and had a lower top speed than desired. Modeled on German and Italian tank designs, this tank featured 3 turrets. Mounted in the central turret was the primary weapon of Type 95, a Type 94 7 cm tank gun specifically designed for it. The cannon could fire both Type 92 high-explosive shells and Type 95 armor-piercing shells. The gun elevation angle was 20 degrees and gun depression angle was -12 degrees. A 6.5 mm machine gun was also mounted in the main turret. Two addition turrets gave Type
Degrees of freedom (statistics) vector (made up of "n" − 1 degrees of freedom within each of the populations). In statistical testing problems, one usually isn't interested in the component vectors themselves, but rather in their squared lengths, or Sum of Squares. The degrees of freedom associated with a sum-of-squares is the degrees-of-freedom of the corresponding component vectors. The three-population example above is an example of one-way Analysis of Variance. The model, or treatment, sum-of-squares is the squared length of the second vector, with 2 degrees of freedom. The residual, or error, sum-of-squares is with 3("n"−1) degrees of freedom. Of course, introductory books on
