"A5", "A6", and "A7" look like they are placeholders for values that were produced but are being hidden from you on purpose. –whuber♦ Mar 31 '11 at 22:02 It's a homework problem. I can do A6 and A7 by myself, I just need some tips on A5. –Patience Mar 31 '11 at 22:28 1 Consider the relationships between SD, variance, and total sum of squares about the mean. –whuber♦ Mar 31 '11 at 22:36 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted I got it! It's the sqrt of residual SS / (n-2). Cheers! share|improve this answer answered Mar 31 '11 at 22:38 Patience 240248 1 In that case it's not the "sample standard deviation," but the residual standard deviation. :-) –whuber♦ Mar 31 '11 at 22:51 I see, thanks for your help :) –Patience Mar 31 '11 at 23:42 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign u

a one-way ANOVA. In Lesson 9 you learned how to compare the means of two independent groups. In this lesson, we will learn how to compare the means of more than two independent groups. This procedure is

known as a one-way analysis of variance, or more often as a "one-way ANOVA."Why not pr f meaning multiple independent t tests?A frequently asked question is, "why not just perform multiple t tests?" If you were to perform multiple independent

## Pr F Statistics

t tests instead of a one-way ANOVA you would need to perform more tests. For $$k$$ independent groups there are $$\frac{k(k-1)}{2}$$ possible pairs. If you had 5 independent groups, that would equal $$\frac{5(5-1)}{2}=10$$ independent t tests! http://stats.stackexchange.com/questions/9023/how-do-i-deduce-the-sd-from-regression-and-anova-tables And, those 10 independent t tests would not give you information about the independent variable overall. Most importantly, multiple t tests would lead to a greater chance of making a Type I error. By using an ANOVA, you avoid inflating $$\alpha$$ and you avoid increasing the likelihood of a Type I error. 10.1 - Introduction to the F Distribution One-way ANOVAs, along with a number of statistical tests, rely on the F distribution. Earlier https://onlinecourses.science.psu.edu/stat200/book/export/html/66 in this course you learned about the z and t distributions. You computed z and t test statistics and used those values to look up p-values using statistical software. Similarly, in this lesson you are going to compute F test statistics. The F test statistic can be used to determine the p-value for a one-way ANOVA. The video below gives a brief introduction to the F distribution and walks you through two examples of using Minitab Express to find the p-values for given F test statistics.Using Minitab and Minitab Express to Find the Area Under the F DistributionThe steps for creating a distribution plot to find the area under the F distribution are the same as the steps for finding the area under the z or t distribution. Remember though that for the F distribution we will always be looking for the right-tailed probability. Later in this lesson we will see that this area is the p-value.Minitab Express MacStatistics > Probability Distributions > Distribution Plot > Display ProbabilityMinitab Express PCSTATISTICS > Distribution Plot > Display ProbabilityMinitab 17Graph > Probability Distribution Plot > View ProbabilityThe video above walks through two examples of finding the p-value in Minitab Express.

page shows an example regression analysis with footnotes explaining the output. These data (hsb2) were collected on 200 high schools students and are scores on various tests, including science, math, reading and social studies (socst). The variable female is a http://www.ats.ucla.edu/stat/spss/output/reg_spss.htm dichotomous variable coded 1 if the student was female and 0 if male. In the syntax below, the get file command is used to load the data into SPSS. In quotes, you need to specify where the data file is located on your computer. In the regression command, the statistics subcommand must come before the dependent subcommand. You list the independent variables after the equals sign on the method subcommand. The statistics subcommand is not needed to run standard deviation the regression, but on it we can specify options that we would like to have included in the output. Please note that SPSS sometimes includes footnotes as part of the output. We have left those intact and have started ours with the next letter of the alphabet. get file "c:\hsb2.sav". regression /statistics coeff outs r anova ci /dependent science /method = enter math female socst read. Variables in the model c. Model - SPSS allows you to anova standard deviation specify multiple models in a single regression command. This tells you the number of the model being reported. d. Variables Entered - SPSS allows you to enter variables into a regression in blocks, and it allows stepwise regression. Hence, you need to know which variables were entered into the current regression. If you did not block your independent variables or use stepwise regression, this column should list all of the independent variables that you specified. e. Variables Removed - This column listed the variables that were removed from the current regression. Usually, this column will be empty unless you did a stepwise regression. f. Method - This column tells you the method that SPSS used to run the regression. "Enter" means that each independent variable was entered in usual fashion. If you did a stepwise regression, the entry in this column would tell you that. Overall Model Fit b. Model - SPSS allows you to specify multiple models in a single regression command. This tells you the number of the model being reported. c. R - R is the square root of R-Squared and is the correlation between the observed and predicted values of dependent variable. d. R-Square - This is the proportion of variance in the dependent variable (science) which can be explained by the independent variables (math, female, socst and read). This is an overall measure of the str
