Time Series Plot
Time Series Plot is one of the most commonly used Data Visualization Tool and perhaps one of the most used ones.
This plot is helpful when one seeks to understand process performance in a time interval.
Time Series like many Data Visualization Plots offers several choices:
time series 1 Options
Options in Time Series Plot:
1: Simple – Used when you have single subgroup data and you would want to understand behaviour in the same in a time interval.
Eg, if you have information of handling time per day. You may want to understand patterns in your data which could be attributed to time, you would use the Time Series Plot
2: With Groups – Used when you have numeric data (preferably continuous) and you have factors which are categorical. This option is used you would want to understand the behaviour of some numeric data by subgroup or factor.
Eg : If we have Handling time data and there are two work types that we have. This option can be put to use to create time series plot by subgroup for comparison and study purposes.
3: Multiple – This option is used when you want more than 1 numeric data for the same time stamp for comparison.
Eg: if I have handling time data for 3 months and I would want to study them together.
4: Multiple with group: When you have more than 1 numeric data and have factor that corresponds to both, and you are looking at using them together.
Eg. If the handling time data for 2 months is to be used along with some categorical data like gender.
Making Time Series Plot on Minitab
A new dialogue box would open for you to choose the option of the Time Series.
Making the Simple Plot
Choose the data that you would want to study.
Add time stamp to make the Time Series plot more meaningful
Adding stamps in time-series
Option 2: With Groups
Time Series with groups
When you hit ok, a new dialogue box would open.
Remember to add the time stamp to get more meaningful information.
