Formula for average pay by gender

HI, Student986394 

Based on your information, I create a saple table:

Then create a column, try the following DAX expression:

AgeGroup = SWITCH(
    TRUE(),
    'Table'[Age] >= 20 && 'Table'[Age] <= 30, "20-30",
    'Table'[Age] >= 31 && 'Table'[Age] <= 40, "31-40",
    'Table'[Age] >= 41 && 'Table'[Age] <= 50, "41-50",
    "Other"
)

Create a new measure, here is my dax:

AveragePayByGenderAndAgeGroup = 
CALCULATE(
    AVERAGE('Table'[Pay]),
    ALLEXCEPT('Table', 'Table'[Gender], 'Table'[AgeGroup])
)

Put measure and fields in table visual. Here is my preview:
