I HAVE LOOKED AT THE CUMULATIVE FEQUENCY TABLE EXAMPLE, AND I AM STILL CONFUSED ABOUT HOW TO MAKE MY OWN TABLE. MY TABLE IS FOR SOCCER LEAGUE SIGNUPS AT SCHOOL. I HAVE A GIVEN CHART OF WEEK 1, WEEK 2 AND WEEK 3. ON WEEK ONE, THERE WERE 9 SIGNUPS. ON WEEK 2, THERE WERE 13 SIGNUPS, AND ON WEEK 3, THERE WERE 14 SIGNUPS. I AM THEN PROVIDED WITH A BLANK TABLE TO FILL IN WEEKS13, FREQUENCY, AND CUMULATIVE FREQUENCY FOR EACH. CAN YOU HELP?

You stated the frequency in weeks 1,2,3. For cumulative, you add in the previous weeks. For instance, cumulative frequency in week 2 is (9+13)
