==Description==
 +
*This function gives the sample from a entire range of valus.
 +
*Sampling is used in statistical analysis in which a predetermined number of observations will be taken from a larger population.

''RANDOM'':Here  we have to mention the random Number of Samples.  The number of values is taken from random positions in given array of values. A value can be selected more than once.
 +
''PERIODIC'': Here we have to mention  the Period n at which we want sampling to take place.  Sampling stops when the end of the input range is reached.
 +
*n is  the number of random values that we want in the result.

*Each value is drawn from a random position in the given array, and any number can be selected more than once.

SAMPLING(ar,ty,n,lv)


  • is the array of values.
  • is the type of sampling.
  • is the number of samples
  • and is the logical value.


Description

  • This function gives the sample from a entire range of valus.
  • Sampling is used in statistical analysis in which a predetermined number of observations will be taken from a larger population.
  • The methodology used to sample from a larger population will depend on the type of analysis being performed.
  • In SAMPLING(ar,ty,n,lv), ar is the array of values which contains the population of values to find the sample.
  • ty is the Sampling type either Random or Periodic.

RANDOM:Here we have to mention the random Number of Samples. The number of values is taken from random positions in given array of values. A value can be selected more than once. PERIODIC: Here we have to mention the Period n at which we want sampling to take place. Sampling stops when the end of the input range is reached.

  • n is the number of random values that we want in the result.
  • Each value is drawn from a random position in the given array, and any number can be selected more than once.
  • lv is logical value like TRUE or FALSE.
  • TRUE is indicating the result will display in new worksheet.Suppose we are omitted the lv value it will consider the value as FALSE.
