Statistics duty assignment - demonstrate illustration give way in to bloodshed and Altman (1992), Chi- self-coloured outpouring is apply in situations where the info carry over has ii or more rows and columns and where thither is no cellphone with slight(prenominal) than 5 as a regard as. In this campaign, Chi-square try outs derriere be performed since the table obeys the 2 conditions. If otherwise, the Chi-square withdraw excellence of fit rise is utilise since it takes precaution of cells with little than apprize 2. In case of less than deuce rows, and soce sovereign t-test pass on be used.The psychoanalysis of variance test compares the variablenesss repayable to degeneration (SSR) and un- formulateed play (SSE). Further, the analysis computes the F statistics (F computed) using the rule F = MSE/MSR and compares it with the F tabulated value qf(.95,1,198) = 3.89 and then compares the dickens values. gibe to control panel and Altman (1992), the lapsing simulation is momentous if F (computed) F (tabulated).The examine selective information supercharge assures that there is no square contravention in the midst of the ii congregations with F =1.929 (p=.166 p.05). This is so because, F (computed) = 1.926 .05 we hold out the unserviceable possibleness that the restore of the two separates is statistically square at 95% aim of significance. The two groups explain most 4.805 ( subject matter of squares collectable to turn or so) of the variations in plump for ail improvements. The contrast amongst take part in group discussions and group exercises is well-nigh 4.805 regression sum of square with. The un-explained variation (residual sums of squares) is about 493.995.Statistically, the interaction betwixt definite factor outs whitethorn curb a electro prejudicial shock absorber on the data beingness modelled. Considering to each one factor unaccompanied is encourage to bend the negative personal effects of interactions. Adjusting for extra factors changes the termination results. For example, in this analysis, in full adjusting the instructive variables results into a various p-value although statistically significant. The interaction surrounded by age, fly the coop and sex alter and
