Stem-and-leaf Plots Are Particularly Useful for Large Sets of Data

- April 15, 2022

However as in the more general case no information can be obtained about which variables here PCs are responsible for the. This is particularly useful when the number of retained components is quite high thus requiring the use of several scores scatter plots.

The combination of A at the level and C at the level gives the highest filtration rate.

. If output from statistical packages was included and how that is used to test for assumptions was discussed then stem and leaf displays and box plots may be more relevant. Other useful exploratory analysis tools for factorial experiments include main effects plots interaction plots. Frank Yates made significant contributions particularly in the analysis of designs.

Specifically the interpretation of β j is the expected change in y for a one-unit change in x j when the other covariates are held fixedthat is the expected value of the. A fitted linear regression model can be used to identify the relationship between a single predictor variable x j and the response variable y when all the other predictor variables in the model are held fixed. Using cluster analysis on the scores themselves allows obtaining a direct inspection of clusters in only one graph.

The sections covering stem and leaf displays cumulative frequency polygons and box plots do not seem necessary and they are not included in the material covered later in the text. But Factor A has a large effect on filtration rate when factor C formaldehyde is at the level.
