Google Sheets can be used to find the critical value for an F distribution for a given significance level. For example, to find the critical value (the value above which you would reject the null hypothesis) for α=0.05α=0.05 with dfbetween=3dfbetween=3 and dfwithin=44dfwithin=44, enter
=FINV(0.05,3,44)
Enter this into Google Sheets to confirm you obtain the value 2.816.
You conduct a one-factor ANOVA with 7 groups and 5 subjects in each
group (a balanced design). Use Google Sheets to find the critical
values for α=0.05and α=0.01(report accurate to 3 decimal
places).

Excel can be used to find the critical value for an F distribution for a given significance level. For example, to find the critical value (the value above which you would reject the null hypothesis) for ?=0.05 with dfbetween=3and dfwithin=3, enter =FINV(0.05,3,36) Enter this into Excel to confirm you obtain the value 2.866. You conduct a one-factor ANOVA with 3 groups and 7 subjects in each group (a balanced design). Use Excel to find the critical values for ?=0.02 and...
Find the critical F-value for a one-way ANOVA given: α = 0.01 dfb = 30 dfw = 14 a. 2.72 b. 3.34 c. 4.21 d. 1.98 e. 3.00 In which direction is the F distribution skewed? a. Positively skewed b. Negatively skewed c. No skew If our calculated F is LARGER than our identified critical value from the F-table, what decision would we make about the null hypothesis? a. Reject the null hypothesis b. Fail to reject (i.e., retain) the...
Find the appropriate critical F-value for each of the following using the F-distribution table. a. D 1=12, D2=20, α=0.025 b. D1=20, D2=15, α=0.025 c. D 1=12, D2=20, α=0.01
Finding F critical for Variances Use the F-distribution to find the degrees of freedon for the numerator (d.f.N.), the degrees of freedom for the Denominator (d.f.D.) and the critical F-value Use the closest value when looking up the d.f.N. and d.f.D. in the tables. Test alpha α Sample 1 Sample 2 d.f.N. d.f.D. F critical Right 0.01 s12=37 n1=14 s22=89 n2=25 Two-tailed 0.10 s12=164 n1=21 s22=53 n2=17 Right 0.05 s12=92.8 n1=11 s22=43.6 n2=11

Find the critical value of t from Appendix D for the following situations. Specify the correct degrees of freedom, whether the value is “+/-“ or is “+ or –“ and the df you used in the table if the value isn’t listed. a) N = 32, α = .05, one-tailed independent groups t-test b) N = 28, α = .01, two-tailed independent groups t-test c) N = 26, α = .05, one-tailed independent groups t-test d) N = 41, α...
In Exercises 1-2, (a) identify the claim and state H0 and Ha, (b) find the critical value, (c) find the test statistic, (d) decide whether to reject or fail to reject the null hypothesis, and (e) interpret the decision in the context of the original claim. 1. A meteorologist claims that the median daily high temperature for the month of July in Pittsburgh is 83 Fahrenheit. The high temperatures (in degrees Fahrenheit) for randomly selected July days in Pittsburgh are...
Looking for some help with this stats problem - will give good reviews! Attempts Average: /19 10. Comparing repeated-measures ANOVA to independent-measures ANOVA Aa Aa You are interested in studying how formal language exposure and deafness affect language acquisition. You want to compare three groups: a hearing group, a deaf group that began learning American Sign Language (ASL) before age 1, and a deaf group that did not begin learning ASL until age 1. You are trying to decide whether...
