How do I get summary statistics in R?
R provides a wide range of functions for obtaining summary statistics.
One method of obtaining descriptive statistics is to use the sapply( ) function with a specified summary statistic.
Possible functions used in sapply include mean, sd, var, min, max, median, range, and quantile..
Is weighted mean descriptive statistics?
The notion of weighted mean plays a role in descriptive statistics and also occurs in a more general form in several other areas of mathematics.
If all the weights are equal, then the weighted mean is the same as the arithmetic mean..

What is weighted descriptive statistics in R?
Weighted Descriptive Statistics is an open source (LGPL 3) package for R which provides de- scriptive statistical methods to deal with weighted data.
Assume that x = (x1,x2, \xb7\xb7\xb7 ,xn) is the observed value of a random sample from a fuzzy population.Feb 29, 2016.
What is weighted in statistics?
A weighted average is sometimes more accurate than a simple average.
In a weighted average, each data point value is multiplied by the assigned weight, which is then summed and divided by the number of data points.
A weighted average can improve the data's accuracy..

The methods used to summarize and describe the main features of a dataset are called descriptive statistics.
Measures of central tendencies, measures of variability, etc., which give information about the typical values in a dataset, are all examples of descriptive statistics. - str() - structure of the object and information about the class, length and content of each column. summary() - summary statistics for each column.
