# conf.interval: the percent range of the confidence interval (default is 95%) # na.rm: a boolean that indicates whether to ignore NA's # groupvars: a vector containing names of columns that contain grouping variables # measurevar: the name of a column that contains the variable to be summariezed # Gives count, mean, standard deviation, standard error of the mean, and confidence interval (default 95%). To use, put this function in your code and call it as demonstrated below. Rename the columns so that the resulting data frame is easier to work with.Find a 95% confidence interval (or other value, if desired).

/Graphs/Plotting means and error bars (ggplot2) for information on how to make error bars for graphs with within-subjects variables.) Asymptotic and resampling strategies for assessing and comparing indirect effects in multiple mediator models.

Find the standard error of the mean ( again, this may not be what you want if you are collapsing over a within-subject variable.

Find the mean, standard deviation, and count (N).

It will do all the things described here: Instead of manually specifying all the values you want and then calculating the standard error, as shown above, this function will handle all of those details. #> 4 M placebo 3 -1.300000 0.5291503 0.3055050ДЄ function for mean, count, standard deviation, standard error of the mean, and confidence interval #> 2 F placebo 12 -2.058333 0.5247655 0.1514867 This edition applies to IBM SPSS Amos 22 and to all subsequent releases and modifications. Suppose you have this data and want to find the N, mean of change, standard deviation, and standard error of the mean for each group, where the groups are specified by each combination of sex and condition: F-placebo, F-aspirin, M-placebo, and M-aspirin.

It is more difficult to use but is included in the base install of R. It is easier to use, though it requires the doBy package. It is the easiest to use, though it requires the plyr package. There are three ways described here to group data based on some specified variables, and apply a summary function (like mean, standard deviation, etc.) to each group. You want to do summarize your data (with mean, standard deviation, etc.), broken down by group.

A function for mean, count, standard deviation, standard error of the mean, and confidence interval.
