APLUSA Stats vs MyPanel

3 common statistical tools used to analyze market research results: 1 - CONFIDENCE INTERVAL CALCULATOR 2 - COMPARING TWO PERCENTAGES 3 - SAMPLE SIZE CALCULATOR ----------------------------------------- 1 - CONFIDENCE INTERVAL CALCULATOR Level of accuracy in percentages observed: To conduct market research is to interview (or observe) a sample of individuals. The larger the sample, the greater the statistical accuracy. Confidence interval provides the level of accuracy of a given measure. FOR INSTANCE Upon interviewing a sample of 500 GP’s, 20% are found to be using Product A. So, what is, within the total population, the actual proportion of users of Product A. Assuming 5% risk level*, confidence interval is: • 20% +/-3.5 • [16.5%-23.5%] In other words, there is a 95% probability that the actual percentage of Product A users in the total population of GPs is between 16.5% and 23.5%. ------------------------------------- 2 - COMPARING TWO PERCENTAGES Statistical significance between 2 observed percentages: When comparing opinions (or attitudes) measured on two samples, a significance test is applied. Significance tests provide an indication whether observed percentages are significantly different or not. FOR INSTANCE Upon interviewing a sample of 500 GP’s, 20% are found to be using Product A. Equally, upon interviewing a sample of 150 cardiologists, 25% of those are found to be using Product A. Would such a result suggest that a larger proportion of cardiologists is using Product A? At 5% risk level*, the two percentages observed on these samples are not statistically different. In other words, there is a 95% probability that the actual proportion of Product A users among GPs’ total population is similar to the actual proportion of Product A users among cardiologists’ total population. ------------------------------- 3 - SAMPLE SIZE CALCULATOR Minimum sample size calculations: By taking into account an expected percentage, as well as the corresponding confidence interval, it is possible to calculate the sample size needed for a given market research survey. This application calculates the minimum sample of respondents needed in order to achieve the required level of research accuracy. FOR INSTANCE Research is needed to evaluate the level of use of Product A among anaesthetists. The desired confidence interval is +/-8. Approximately one third of anaesthetists is expected to be using Product A. How many anaesthetists need to be interviewed in order to achieve this margin of error? At 5% risk level*, for an expected percentage of 33%, with a confidence interval of +/-8, minimum sample size is 133 anesthetists. In other words, if you interview a minimum of 133 anesthetists, there is a 95% chance to get a confidence interval of +/-8 if the proportion of Product A users in the anesthetist sample is 33%.

MyPanel is a research app that enables market researchers to conduct quantitative research. The app can be used for different kinds of data collection projects, such as exit interviews, panel research, mystery shopping and field marketing. The app is connected to a closed online platform, where surveys can be created and results can be seen real time. Results can also be downloaded in different CSV and Excel formats. We offer a wide range of question types, such as: - single choice - multiple choice - yes-no - open answer - photo/video question - audio fragment upload - open question - several grids - several rating scales - date/time - divide question - ranking question - location question It is possible to apply skip logic and filters within a survey in order to route respondents through the survey based on their answers. Furthermore, you can show stimulus material to respondents, like text, photos and videos. When filling in the survey, the location of the respondent can be tracked, if the respondent gives permission to send this information. To be able to participate in a research, you need to sign in with your email address and password. You may receive a password through a market research company or recruitment agency. After entering your password and downloading surveys, the app works without an Internet connection. This means that respondents can fill in the survey whenever and wherever they want. Answers are stored locally in the app and are uploaded when there is an Internet connection again.
