Critical Values of Studentized Range Distribution(q) for Familywise ALPHA =05Your q score goes in the first box The number of groups (or treatments, means, etc) in your study goes into the second box And you add the withingroups degrees of freedom to the final box After that, just select your significance level (it defaults to05), and hit the Calculate buttonTukey's posthoc test is a method that is used to determine which groups among the sample have significant differences This method calculates the difference between the means of all the groups Tukey's HSD test values are number which acts as a distance between the groups It works by defining a value known as Honest Significant Difference
STATISTICAL TABLES 1 TABLE A1 Cumulative Standardized Normal Distribution A(z) is the integral of the standardized normal distribution from −∞to z (in other words, the area under the curve to the left of z) It gives the probability of a normal random variable not being more than z standard deviations above its meanTukey Q Calculator This tool will calculate critical values (Q05 and Q01) for the Studentized range distribution statistic (Q), normally used in the calculation of Tukey's HSD The calculator is easy to use Just input the number of groups in your study (k) in the first box, and degrees of freedom (normally the total number of subjects minus the number of groups) in the second boxJohn Tukey made a system for managing multiple comparisons in ANOVA that still keeps the experimentwide error at or below set significance level (eg 005) without maintaining as much power as possible
The bottom (bold) value is α =01 The number of treatments is listed across The df for the error term is in the left column, where the "error term" is another name for the withintreatments variance Now, use the q value to calculate Tukey's HSD The widespread use of 'statistical significance' as a license for making a claim of a scientific finding leads to considerable distortion of the scientific process (according to the American Statistical Association) We review why degrading pvalues into 'significant' and 'nonsignificant' contributes to making studies irreproducible, or to making them seem• Untuk mencari nilai q005(6, 24) kita dapat melihatnya pada tabel Sebaran studentized range pada taraf nyata α = 005 dengan p = 6 dan derajat bebas (v)= 24 Perhatikan gambar berikut untuk menentukan qtabel • • Dari tabel tersebut kita dapatkan nilai nilai q005(6, 24) = 437 • Hitung nilai HSD dengan menggunakan formula berikut •

The pvalue from the ANOVA table is Since this pvalue is less than 05, we can reject the null hypothesis and conclude that the means between the three groups are not equal To determine exactly which group means are different, we can perform a TukeyKramer post hoc test using the following stepsUsing the Studentized Range q Table with α =05, k = 4 and dfW = 44, we get qcrit = Note that since there is no table entry for df = 44, we need to interpolate between the entries for df = 40 and df = 48 Alternatively, we can employ Excel's table lookup capabilities My question is how can we obtain a Tukey upper quantile table(for studentized range distribution) table using qtukey function?(The table is like Tukey Table) (dfrange=10,nurange=,alpha=005,digs=3){ ROWS

The multiple comparison method Choose the comparison procedure based on the group means that you want to compare, the type of confidence level that you want to specify, and how conservative you want the results to be "Conservative" in this context indicates that the true confidence level is likely to be greater than the confidence level thatTable A8 Critical values (at 5% and 1% significance levels) for Duncan's Multiple Range Test α = 05 Number of consecutive means ( p ) to be comparedThe table below reports the aforementioned ANOVA omnibus test Our null hypothesis is that the population means are equal for all medicines administered P ("Sig") = 0000 way less than 005 so we reject this hypothesis the population means are not all equal Some medicines result in lower mean BDI scores than other medicines
INTERPRETING THE ONEWAY ANOVA PAGE 2 The third table from the ANOVA output, (ANOVA) is the key table because it shows whether the overall F ratio for the ANOVA is significant Note that our F ratio (6414) is significant (p = 001) at the 05 alpha level When reporting this finding – we would write, for example, F(3, 36) = 641, p < 01 The F indicates that we are using an F test (ieQTable Numbers in the far left column are degrees of freedom Numbers in the second column are significance levels (alpha) Blue numbers in the top row refer to the number of groups df24 rows TABLE B5 The studentized range statistic (q)* *The critical values for q corresponding to alpha = 05 (top) and alpha =01 (bottom)
