Cumulative proportion refers to the proportion of a piece of data in the overall data, which is usually used to reflect the importance or distribution of the data in the whole. The cumulative percentage is calculated by comparing the data to the sum of all previous data to calculate the proportion of all data before the data location to the total.
The specific calculation method is as follows:
1.Determine the scope and order of the data. First of all, it is necessary to determine the scope and order of the data to be calculated to ensure the accuracy and comparability of the data.
2.Calculate the cumulative percentage. For each data point, add up all the data before it and divide it by the total amount of data in the population to get the cumulative percentage of that data point.
3.Draw a chart. To better show the distribution and trend of the data, you can plot the calculated cumulative proportion data into a chart, such as a line chart or a bar chart.
The cumulative percentage calculation method can help us understand how the data is distributed in the population and help us spot outliers or trends in the data. In practice, the cumulative proportion can be used for data analysis in various fields, such as market share, user activity, sales, and so on. By analyzing the cumulative proportion of data at different time nodes or in different regions, we can better understand the needs and behaviors of the market or users, so as to formulate more scientific and reasonable data analysis plans and decision-making basis.
