I asked 6 random people how many countries they have been to before and this is what they reported:
Data Set:
0, 1, 1, 3, 7, 9
You need to go through the 5 steps of calculating sample standard deviation for this data set. Remember to not round anything inbetween (it won't be necessary for this problem) until you get to the final asnwer and then round your final answer to the nearest tenth.
