For a sample of n = 36 that has a sample variance of 1,296, what is the estimated standard error for the sample? 6 37 36 6. 9
Liula [17]

The estimated standard error for the sample is 6

Given,

Sample size, n = 36

Sample variance, s^{2} = 1296

Standard deviation, s = √1296

                                   = 36

Standard error, SE = \frac{s}{\sqrt{n} }

                              = \frac{36}{\sqrt{36} }

                              = \frac{36}{6}

                              = 6

Concept

  • Sample size is the number of participants or observations included in a study. It is denoted by ‘n’
  • Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by 's^{2}'
  • Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’
