Many businesses use some sort of statistics in their day-to-day operations. Researchers need power analysis for a variety of projects. Software can help when conducting your power analysis.
1. Power Analysis
Statisticians use power analysis to calculate statistical parameters based on others already calculated. Four parameters are sought in a research plan. The statistician needs to know the sample size, probability of finding significance where there is none, the expected effect and the probability of finding true significance. They can determine some of these parameters based on prior studies. If no previous study exists, a pilot study should be conducted. While many statisticians can use the long-hand method of solving for the fourth needed parameter, power analysis software takes some of the work out of calculating.
2. Easier Research
Software can take your power analysis to new levels. It can speed up the time by not having to calculate everything by hand. If you already know three of the four parameters, you can plug in the variables and make various calculations. Reports are available to print summarising the various findings. Graphs and tables are available to place in the reports for a professional finished product. Instead of working everything out by hand, the software allows you to keep track of your tests, resources and data. You can view a variety of recordings in scatter plots and event logs.
3. Software Availability
The software is available for purchase or for rent. Most models are easy enough to use for one-time renters. For large institutions and research firms, owning the software may be more cost-effective. The software incorporates with a variety of well-used software including Microsoft Excel for easy transfer.
Present your findings in a clear, concise, professional way with the right software for your research plan. Whatever you’re researching, have the right tools to make your job effective and efficient.
