It is a wonderful program to use now that I have figured out what today. It is very easy to move around in the program too. Thank you for the intro videos too!

I first tried PDFfiller with a trial subscription and to be honest, I really just wanted it so I could add text to a document and I didn't plan to extend my subscription. But after trying it, I liked it so much, I continued the subscription after the trial and my subscription expires in 2 days and I plan to renew for another year. I'm a freelance paralegal and often need to add text (and complete forms) in .pdf format. The program is also very easy to use and has many great features (like "erase" and different font styles and sizes). My subscription has more than paid for itself and I would - and do - highly recommend PDFfiller to anyone looking for this type of program.

How do you know if a statistic is reliable?

What is a misleading statistic?
Misleading statistics, on the other hand, is a term that refers to the misusage of numerical data, either intentionally or due to error, that results in misleading information. Misleading statistics can deceive the receiver of the information if the receiver is not careful to notice the error or deception.
Can statistics be wrong?
That is, a misuse of statistics occurs when a statistical argument asserts a falsehood. In some cases, the misuse may be accidental. In others, it is purposeful and for the gain of the perpetrator. When the statistical reason involved is false or misapplied, this constitutes a statistical fallacy.
Why do statistics need to be accurate?
Statistics allow you to evaluate claims based on quantitative evidence and help you differentiate between reasonable and dubious conclusions. That aspect is particularly vital these days because data are so plentiful along with interpretations presented by people with unknown motivations.
How do you determine if there is a statistically significant difference?
Statistical Significance The difference between two groups (such as an experiment vs. control group) is judged to be statistically significant when p = 0.05 or less. At p= 0.05, the differences between the two groups have only a 5% probability of occurring by chance alone.
How do you know if a sample size is statistically significant?
Population: The reach or total number of people to whom you want to apply the data. Probability or percentage: The percentage of people you expect to respond to your survey or campaign. Confidence: How confident you need to be that your data is accurate.
How do you know if two numbers are significantly different?
The t-test gives the probability that the difference between the two means is caused by chance. It is customary to say that if this probability is less than 0.05, that the difference is 'significant', the difference is not caused by chance.
