I am using SPSS ver 26 on Windows. I discussed this with my statistics teacher, and he said my data could not be tested statistically in SPSS. He told me my sample was small. 

I should have analyzed this data until multivariate. I have tried to analyze my data, and normality, homogeneity, and non-parametric tests resulted in no influence between "age" and "X, Y, Z." " My teacher said the results of this data cannot be continued at the multivariate stage because the data is not homogeneous. He tried to use the linearity test, but the sig. Value did not appear / blank. 

I needed clarification because my teacher told me to analyze descriptively, not statistically. 
I need some clarification. Is there anyone who can help me? I accept all suggestions and criticism.
