I am trying to check variable importance of this gender variable. I know if p value is less than 0.05 then its important otherwise not but what is it's giving p-value < 2.2e-16. I have tried other methods too but giving the same for all of the categorical variable. I have pasted output for only one variable. SO, how to interpret this. (variable to be considered or not).
Frequency of my data points
table(data$gender,data$target) Output: N Y F 2107566 2560932 M 1307442 1567399 U 3 16
To test statistical significance score:
chisq.test(table(data$gender,data$target)) Output: Pearson's Chi-squared test data: table(data$gender, data$target) X-squared = 86.9407, df = 2, p-value < 2.2e-16
Note : I think one of the possible reason might be because of 7.5 million rows. So, will this be solved by sampling the data for checking the significance.
