Help!!! can someone answer and explain using formulas The following data were obtained from an independent-measures research study comparing three treatment conditions. Use an ANOVA with alpha = .05 to determine whether there are any significant mean differences among the treatments. (Round your answers to two decimal places.)

Solution

Overall mean = 128+144+128/18 = 400/18 = 22.22

SSTR = 8(16-22.22)^2+6(24-22.22)^2+4(32-22.22)^2

=8(38.69)+6(4.93)+4(95.65)

=309.52+29.58+382.59

= 721.69
