I have done a survey and I need to calulate the mean, median and mode for my data. To try and determine an average divorce rate I interviewed 15 married people, 8 females, 7 males. I asked each person how many times they had been divorced. 10 people said 0, and 5 people said 1. I am unsure how to caculate the mean, median and mode with this data. Please help.
Hi Pam. I see you edited your question. Let me adjust my answer.
The mean is the sum of all your data divided by the number of data points. You have 15 answers. The sum is 10 x 0 + 5 x 1 = 5 divorces.
5/15 = 1/3 ≈0.33. This is your mean divorce per person.
To get the median, line up the data in order and find the middle data point:
0, 0,0,0,0,0,0,0,0,0, 1, 1,1,1,1
0 is in the middle and is the median. The mode is the most frequent occurring data point--in this case, 0 occurs 10 times, which is more than any other value. 0 is your mode.
Old answer (when you had yes/no data):
You have categorical data. No mean or median can be determined. The mode is simply the most frequent response. In your case, the mode is "NO, I have not been divorced." That's all there is to it.
The median and the mean can ONLY be determined if there is a quanitative component to your variables. For example, you could have asked "How many times have you been divorced?" The people surveyed could say 0, 1, 2, 3, 4, and so on. This would be discrete quantitative data that does have a mean and a median. But that is not what you presented here with your "yes/no" data.
