# Data Analysis Plan for Analysis of Variance (ANOVA)

Do you have the data with more than two, three, or even five level independent variables? And do you have one categorical (dependent) and several quantitative variables? And you struggle to understand how these variables interact with each other and in turn impact dependent variable? Is the data normally distributed? Are sample sizes being equal? Then Analysis of Variance (ANOVA), a parametric test based on the normal distribution would be the best choice for your data. As it enables researcher to evaluate all the mean difference in a single hypothesis testing using a single alpha level, therefore, risk of Type I error is under control. The hypothesis assumed is that all group means are equal. H0: μ1 = μ2 = μ3 = . . .. However, it does not indicate exactly which groups are different. But we can certain tests like Post Hoc test to examine the significance within groups.

School 1 (most deprived; 40% subsidized lunches).

b School 2 (medium deprived; <10% subsidized).

c School 3 (least deprived; no subsidization, private school).

d ANOVA; significant differences are highlighted in bold (P<0.05).

#### Reporting Results of one way ANOVA [Interpretation of one Way ANOVA)

“An analysis of variance showed that the effect of noise was significant, F (3, 27) = 5.94, p = .007. Post hoc analyses using the Scheffé post hoc criterion for significance indicated that the average number of errors was significantly lower in the white noise condition (M = 12.4, SD = 2.26) than in the other two noise conditions (traffic and industrial) combined (M = 13.62, SD = 5.56), F(3, 27) = 7.77, p = .042”.

#### What we will deliver when you order for ANOVA Statistical Analysis Help

Ordering ANOVA statistical Analysis help for your dissertation, publication or presentation for your papers from StatsWork research writing services is simply easy and straightforward. You will get the reply within 30 minutes which would enable to place your order quickly without any delay in submissions. We would provide the work in the following structure.

At Stats Work, we help to analyze your data and present in a journal format and interpret the results using standard formatting like APA, rather than merely copy pasting the results. The following are the output that we provide while you request for one-way Analysis of Variance

• Measuring Effect Size η2
• Box Plots, if required
• The Test statistics (F- ratio, t-value, z-scores)
• The degree of Freedom
• The p-value (Significance value, a priori or a posteriori alpha level: α)
• Bonferroni / A Holm / A Hochberg Correction
• Tukey and Sheffe Test

To run ANOVA, we use various tools like SPSS, SAS, R, Minitab, and STATA any specific tools that you request will be utilized to generate and present the analysis.
