nQuery Reviews & Product Details

This software handles every design of importance to me. I am a consulting statistician in the pharmaceutical industry and I have a vast variety of study designs that I must provide sample size analysis for. NQuery walks me through the issues and provides excellent guidance as well as references. Review collected by and hosted on G2.com.

Some advice appears when you hover over a specific part of a table. I have missed some advice at times. It would be an improvement to have warning boxes or other methods of providing dynamic advice. Review collected by and hosted on G2.com.

nQuery provides a great interface to quickly access the desired methods for sample size calculation and useful tips to provide the desired inputs. It further allows for swift visualization of results to indicate how changing parameters impact sample size and power - a very useful tool to convey results of the sample size calculation.

Another useful feature are side-tables that allow the user to easily populate the main table for sample size calculation without having to go to length to obtain the required values. The variety in methods that are available for sample size calculation enable the tool to be used in most trials.

While not part of the nQuery sample size software, I would also like to mention the webinars provided by nQuery that not only provide information regarding their software but also well prepared information on various topics; and that for free. Review collected by and hosted on G2.com.

If I had to pick something to dislike, I would say that the business model (restricting a few methods to certain licenses of the software) is not my favorite. But the fact that there are all of these methods is much rather a plus. Review collected by and hosted on G2.com.

it has a broad selection of tools in calculating sample size and power. the menus are easy to follow and the help icons on each screen help you navigate very well through the calculation. great for academicians and able to take some detail in its calculations.

i have no dislikes. i may just need to expand my knowledge on sample size calculation to fully appreciate the app Review collected by and hosted on G2.com.

There are a large number of options for designating assumptions such equal or unequal variance.

There are assistants to estimate standard deviation and covert parameters

Plots can easily be obtained to show patterns of sample size.

There are new Bayesian assurance options.

Every cell has a help page that automatically displays.

A default output statement is created automatically that is appropriate for inclusion in a study protocol or a journal article. Review collected by and hosted on G2.com.

Some of the help pages are cryptic.

I use a Mac platform. I must run nQuery in a Windows emulator. Review collected by and hosted on G2.com.

The range of procedures. Their website says 1000+ sample size scenarios, and I have to say while working internal and externally with this tool for on our protocol, we have been able to test and validate any of our adaptive trial designs so far. I am a long time user so was using nQuery as my sample size software tool before it had Bayesian and Adaptive capabilities. So I really like the addition of them in the last few years.

There is nothing the warrants me to say I dislike any particular feature. It does what I need of it quickly. Review collected by and hosted on G2.com.

Intuitive, easy to use software for all kinds of power analyses. Great for academic settings. Excellent support: always available, fast response, very friendly, thinking with you and taking the specifics of the client's needs seriously. Review collected by and hosted on G2.com.

Quite elaborate; takes time to learn to use it. Review collected by and hosted on G2.com.

The very wide range of procedures available for sample size determination. During my day as bio-statistician in the Faculty of Health Sciences of our university I am often involved with protocol development, mainly in clinical research, for Masters & PhD students as well as for established researchers . The protocols for these projects all require a sample size statement, and for the latter I am very grateful for a wonderful tool line nQuery. I also serve on an ethics committee, primarily serving pharmaceutical research, and again nQuery enables me to confirm the sample size statements in the protocols on review.

I do not have dislikes. My battles are usually due to my own limitations. Review collected by and hosted on G2.com.

I provide statistical consultation for various clinical programs that involve protocol development, randomization, assessments of sample size calculations, efficacy evaluations and study data review. I like them all to use the same software. Most researchers I work with are already familiar and skilled with nQuery. I like that trust and time saving this software brings.

I had some trouble getting everything going, but i am just not very good with computers. Lukiliy the helpdesk is fabulous! Review collected by and hosted on G2.com.

Using the users manual and with a basic knowledge of statistics I am able to very easily able to calculate sample size for planning and conducting clinical studies. Review collected by and hosted on G2.com.

I have figured out how to print all the reports yet. Review collected by and hosted on G2.com.
