I Is a random sampling which uses a 11st 01 all the elements in the population and then elements are being selected based on the kth consistent intervals. To get the kth interval, divide the population size by the sample size.

All elements of the clusters randomly selected are considered the samples of the study. 0 Simple Random Sampling 0 Systematic Sampling 0 Stratified Sampling 0 Cluster Sampling 2 points the following are scores of students: 9, 7, 8, 9, 7, 5, 8, 10, 7, 8, and 10. What is the value of u? (2 points) A. 7 C. B. 7.33 D. 1 point is a random sampling wherein the population is divided into different strata. Selection of samples will be pmportionately randomly picked in each stratum that is why all strata have representatives in forming the samples. 0 Simple Random Sampling 0 Systematic Sampling 0 Stratified Sampling 0 Cluster Sampling is the most basic random sampling wherein each element in the population has an equal probability of being selected. They are usually represented by a unique identication number that is written on equal-sized and shaped papers and then selection of samples is possible through the lottery method. Random numbers selected to decide which elements are included as the sample. The drawing number of papers is based on the desired number of samples. 0 Simple Random Sampling 0 Systematic Sampling 0 Stratified Sampling 0 ClusterSampling (D This is a required question 'I point What do you call a number that describes a population characteristic?
