This method is particularly useful when the population is large and a simple random sampling would be too cumbersome or time-consuming.<\/p>\n\n\n\n<p>In the case of option c, selecting every 20th person from a directory illustrates systematic sampling because it involves an ordered list (the directory) and a fixed interval (every 20th person). This method ensures that the sample is spread evenly across the entire population, which can help reduce bias and provide a representative sample. The starting point is usually randomly selected, and then the selection continues at the set interval, making the process efficient and straightforward.<\/p>\n\n\n\n<p>Conversely, the other options do not qualify as systematic random samples:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a.) Choosing 10 marbles from a jar containing 40 marbles.<\/strong> This is a simple random sample if each marble has an equal chance of being chosen, but it does not involve a systematic approach or a fixed interval.<\/li>\n\n\n\n<li><strong>b.) Picking out 10 names from a group of 50 students.<\/strong> Similar to option a, this represents a simple random sampling method if done randomly, but it lacks the systematic structure.<\/li>\n\n\n\n<li><strong>d.) Selecting one card from a deck of 52 well-shuffled cards.<\/strong> This option describes a simple random sample where each card has an equal chance of being selected, rather than following a systematic procedure.<\/li>\n<\/ul>\n\n\n\n<p>In summary, option c demonstrates systematic random sampling because it involves a fixed interval in the selection process, making it distinct from the other options provided. This method is beneficial in achieving a sample that is both random and evenly distributed across the population.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of these is an example of systematic random sample?a.) choosing 10 marbles from a jar containing 40 marbles.b.) picking out 10 names from a group of 50 students.c.) picking out the telephone number of every 20th person from a directory.d.) selecting one card from a deck of 52 well-shuffled cards.
