Characteristics of a population are called:
A: parameters
B: statistics
C: estimates
D: variance
A: parameters
B: statistics
C: estimates
D: variance
举一反三
- When estimating population parameters, a point estimate is:? always equal to a population value.|a range of possible values for a population parameter.|the population mean.|a statistic that estimates a population parameter.
- A portion of the population selected to represent the population is called A: statistical inference B: descriptive statistics C: a census D: a sample
- The range of variation is the acceptable parameters of variance between actual performance and the ideal.
- The sample variance is an unbiased estimator of the population variance.
- The degrees of freedom in the calculation of the population variance is n -- 1.
