What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I had to amend my 2014 federal taxes, and when I went in to the form, it brought me onto your site. I filled out the form and went to print when I found out that there was a cost for the program. I only needed the program for a short amount of time. I will be cancelling the program as soon as my amended tax forms are completed and the IRS is satisfied.

Great functionality, may need some better guidance on how to do various tasks from the very basic and simple (extract a single table into excel) to the most advanced

Perfect Software for Small Business
I use this software for my home inspection business to create required insurance reports and include images. It allows me to upload the required insurance form, edit it and add images for the required mitigation and four-point inspection reports. I love that I am able to save my reports, reuse them by editing as needed and organize them in the straightforward filing system.
Excellent value for all of the features offered. Easy to use and manage organization. Love the FAX feature, signature, editing and capacity to upload images.
Flash feature for uploading images. Settings have to be set and sometimes reset themselves. I use this feature everytime and sometimes the software freezes.

Absolute perfection
Absolute perfection. Saved my butt a multitude of times when procrastination had me in its violent and deadly grip. I love you all and wish you the best in life. When I become a billionaire I will retire you all if this beauty of an app hasn't done that already. Xoxoxoxo

Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed the 1year subscription. Advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. They communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month and cancelled my future subscription. I would happily use this again. Thank you.

How do you standardize a number?
Typically, to standardize variables, you calculate the mean and standard deviation for a variable. Then, for each observed value of the variable, you subtract the mean and divide by the standard deviation.
How do you standardize a sample mean?
We subtract off the mean of X, which is, and divide through by the standard deviation of X, which is n, to obtain a standardized version of the sample mean: X/n.
How do you standardize a mean?
Typically, to standardize variables, you calculate the mean and standard deviation for a variable. Then, for each observed value of the variable, you subtract the mean and divide by the standard deviation.
How do you tell if a sample mean is normally distributed?
Distribution of the Sample Mean. The statistic used to estimate the mean of a population,, is the sample mean, If X has a distribution with mean, and standard deviation, and is approximately normally distributed or n is large, then is approximately normally distributed with mean and standard error .
How do you tell if a sample is normally distributed?
The black line indicates the values your sample should adhere to if the distribution was normal. The dots are your actual data. If the dots fall exactly on the black line, then your data are normal. If they deviate from the black line, your data are non-normal.
What is the distribution of the sample mean?
The Sampling Distribution of the Sample Mean. If repeated random samples of a given size n are taken from a population of values for a quantitative variable, where the population mean is (mu) and the population standard deviation is (sigma) then the mean of all sample means (x-bars) is population mean (mu).
Is the distribution of sample means always normal?
When the distribution of the population is normal, then the distribution of the sample mean is also normal. For a normal population distribution with mean and standard deviation, the distribution of the sample mean is normal, with mean and standard deviation.
How do you find the sample mean from population mean and standard deviation?
Step 1: Calculate the mean of the data this is in the formula. Step 2: Subtract the mean from each data point. Step 3: Square each deviation to make it positive. Step 4: Add the squared deviations together. Step 5: Divide the sum by the number of data points in the population.
