# Minitab Data Sheet Setup

Hey everyone,

A bit stuck, attempting to do a statistical analysis for this research paper for my undergrad. I am basically looking at 3 variables: major axis, minor axis, and area.

These three variables are from a shotspread. Basically looking at shotgun pellet dispersion from different positions. I have 10 sets of data for each position. The positions are based on different angles and distances. The distances: 0.02, 0.5, 1, 2, and 4 m, and each distance shot at the angles of: 90, 60, and 30 degrees.

I would think that this is best done with a MANOVA, just not sure how to do it. Basically I want to check if the major, minor, and area for each position can be differentiated from that of another position.

Any help would be greatly appreciated. I just want to see if it is possible, based on those variables, to predict a shooter position. So I want to make sure that at least one of the three variables is significantly different. Thanks so much, been stuck for ages

This response may be too late for you, but you set up and analyze a MANOVA in Minitab the same way that you do for an ANOVA. This will tell you if any of the three factors are significant. There is an option within the MANOVA dialog boxes that will allow you run follow-up univariate ANOVAs to determine which of the three are significant.

Enter major axis, minor axis and area as the Responses. Enter distance and angle as the model. Enter distance and angle again as random factors as you are not interested in those exact distances and angles, but are using them to represent all possible distances and angles within the design space.
