Dear Experts,
I have developed an X-Bar control chart from a process measurement variable with Date hh:mm format, the range of my data between 0:00 and 9:40, the chart gave me a central line with average = 7361.02, and a y-axis from -5104 till 19826.
May I know where the mistake and how to solve it?
Thanks.
Omar.
