Considering a sample of turkeys weighed at 8 weeks of age have the following weights in ounces- 161 , 172 , 155 , 173 , 149 , 177 , 156 , 174 , 158 , 162 , 171 , 181 calculate the mean, variance, and standard deviation. Introduction: Mean is a model of a given data set. It is the value that is the most common in a given set. Mean or average of a sample is calculated by summing all the values in the sample and dividing them by the total number of individuals in the sample (n). Variance is a numerical measure of the spread of the distribution around the mean. This is calculated to determine how much variation exists among individuals in the sample. It is calculated by summing the square of the difference between each individual value and the sample mean and dividing that sum by the number of degrees of freedom in the sample. Standard deviation describes the distribution of data. It is calculated as square root of variance.
