Answer:
Array
Explanation:
The array is a data structure in C that can hold a predefined quantity of the same type of element in an ordered fashion, and can be defined with the following syntax: type name[amount] = {elements}; where type is the type (like int), amount is the capacity it should be defined at, name is what you want to name the array, and elements are a comma separated list of elements to initialize the array with. You can also change the values of elements by using this syntax: name[index] = newelement; where index is which index to change, and new element is what to set it to.

Calculate the standard deviation for the following data set: Data set: 4, 14, 6, 2, 7, 12
Answer:
4.2328083664001
Explanation:
standard deviation is the square root of the variance. It is one of the measures of dispersion, that is a measure of by how much the values in the data set are likely to differ from the mean
Standard deviation formulas
The formula for the standard deviation of a sample is:
$ s =\sqrt{\frac{1}{n-1} \sum_{i=1}^n (x_i-\bar{x})^2$
where n is the sample size and x-bar is the sample mean.
The formula for the standard deviation of an entire population is:
$ \sigma =\sqrt{\frac{1}{N} \sum_{i=1}^N (x_i-\mu)^2$
where N is the population size and μ is the population mean.
