| Posted: 26 Dec 2012 05:55 PM PST Cumulative Probability Plot
This tool helps you to create cumulative probability chart from your data. To do this, we sort your data in ascending order. Next, we calculate percentile rank from your data. The smallest number in your data has the smallest percentile. Then we plot your sorted data versus percentile rank. You can do it easily in Excel. However, this useful web tool can help you to build cumulative probability chart up to 5 series, instantly, all in one chart! So you can compare your data side-by-side. This chart is also called percentile rank plot. We build this web tool using jquery and JavaScript plot. We have tested this web tool using Firefox, Chrome, Safari, Opera and IE. Definition of percentile rank. A percentile rank is typically defined as the proportion of scores in a distribution that a specific score is greater than or equal to. For instance, if you received a score of 90 on a math test and this score was greater than or equal to the scores of 80% of the students taking the test, then your percentile rank would be 80. You would be in the 80th percentile. How to use this tool?
In this tool we provided example showing initial production of 300 wells from 5 different operator. Total data in this example 1500 points. You can use this tool to analyze percentile rank of your own data. Tips: No need to sort your data. Numbers with comma thousand separators are allowed. Tested up to 15,000 points (3,000 points for each series). Let us know if you are able to use this tool with more than 15,000 data points. Show data point when hovering the mouse over a data point on a chart. Link to web tool: Cumulative Probability Plot Related Posts:
