Problem
Plan for analysis and use of data-do not describe specific statistical analyses unless you are sure you know what you are describing. If you plan to compare the results of two groups, you do not have to specify that you will use ANOVA or t-tests to do so--just tell me you will compare the results of the two groups and that will usually suffice. This part should also address what you expect to find, what the significance of your findings will be for social work practice, and what the weaknesses/limitations of your design are and what you might do if you had more time and resources.
My hypothesis is do younger children have lower lengths of stay in the foster care system than older children?
