Statistics are mathematical measures of data. There are two basic types: descriptive statistics, which are based on data from the entire population being studied; and inferential statistics, which are based on a sample representing the population being studied...
I was in charge of a project that needed to be completed by a certain date in order to meet the client’s expectations. However, due to unexpected delays, we were not able to meet the deadline and so I had to make a difficult decision. I decided to extend the deadline, but I had...
By default,mfxcalculates the marginal effects at the means of the independent variables. To calculate the marginal effects at the medians, type . mfx compute, at(median) To calculate the marginal effects at zeros, type . mfx compute, at(zero) ...
Output - Test Statistics TableExact Sig. (2-tailed) refers to our p-value of 0.24. This means there's a 24% chance of finding the observed difference if our null hypothesis is true. Our finding doesn't contradict our hypothesis is equal population medians. In many cases the output will...
Both descriptive and inferential statistics are types of statistical analysis used to describe and analyze data. Here are the main differences between them:Definition Descriptive statistics use measures like mean, median, mode, standard deviation, variance, and range to summarize and describe a data ...

To understand the quartile, it is important to understand themedianas ameasure of central tendency. The median in statistics is the middle value of a set of numbers. It is the point at which exactly half of the data lies below and above the central value. The median is a robust estimator...
