Pearson Chi-square test
Bivariate - cat. scale - Stat?
T-test -> compare 2 means
ANOVA -> more than 2
Bivariate - scale scale - Stat?
T-test for corr=0
when agglomerative hierarchical cluster?
- we want to know about the agglomeration process (similarities and diff. between groups).
- Limited cases.
- Homogeneous set of data - all scale or categorical.
How hierarchical cluster?
> Analyze > Classify > Hierarchical Cluster > var. in ‘Variable’ > ind. var. in ‘Case label variable > Statistics: Proximity Matrix, Agglomeration schedule if you want a specific # Clusters: Cluster Membership > Plots: Dendogram, Icicle=None > Method: Centroid Clustering, Squared Euclidian Distance if var. are diff in size - Transform > Standardize
To explore groups > Save clustership > Analyze > Compare Means > Means > clust. var. in ‘Dependent List’ > ind. var. in ‘Independent List’
To know stat. sig. > ANOVA
How bar graphs?
> Graphs > Legacy Dialogs > Bar > clustered or stacked > categorical v. in ‘Category axis’ > v. diff. section in ‘Def. stacks by’ > numerical v. in ‘Columns’
how pie chart?
> Graphs > Legacy Dialogs > Pie > summ. for groups > Define
How boxplot?
> Graphs > Legacy Dialogs > Boxplot > scale v. in ‘Variable’ >
How scatter?
> Graphs > Legacy Dialogs > Scatter/Dot > indep. v. in ‘Row’ > dep. v. in ‘Column’
