英国南安普顿代写作业:计划人口

“人口”指的是所有可能被纳入研究的人。就我的研究计划而言，我的人口将是孤儿。这是因为有了孤儿，阶级背景不会成为影响因变量的变量，也就是教育程度。如上所述，我的实验需要两组五名学生。这些学生必须尽可能的相似:相同的年龄，相同的性别，相同的班级背景，相同的学术能力。因此，孤儿所需要的标准是，他们必须是高中最后一年的男学生，最重要的是，他们以前从来没有服用过任何娱乐药物。由于我的人口不是很大，我只对找到10个容易被研究的学生感兴趣，所以在这里取样不是问题。在找到所有符合要求的孤儿后，他们都将接受一项学术测试，以检查他们的学业成绩。将选出10名具有最佳和相同学术能力的学生。然而，如果有超过十个学生有相同的分数，那么将会选择一个随机抽样程序以避免任何偏差。一个简单的随机抽样程序保证每个学生都有均等的被选中的机会。为了减少浪费时间和避免偏见，把所有学生的名字都放在一个盒子里，然后把需要的名字写出来。选出十个学生后，把他们分成两组。一组为对照组，另一组为实验组。

the term 'population' refers to all those people who could be included in a research'. In the case of my research proposal, my population will be the orphans. This is because with orphans, class background will not be a variable that might affect the dependent variable, which is the educational attainment. As mentioned above, I will need two groups of five students for my experiment. These students must be as alike as possible: same age, same gender, same class background, and same academic abilities. The criteria therefore that are required in the orphans are that they have to be final year male students in high school, and most importantly they have never ever taken any recreational drugs before. Since my population is not a large one and I am only interested in finding ten students which are easily studied as a whole, sampling is not an issue here. After finding all the orphans with the required criteria, they all will be given an academic test to check their academic performance. Ten students with the best and same academic abilities will be chosen. However if there are more than ten students with the same marks, then a random sampling procedure will be selected to avoid any bias. A simple random sampling procedure guarantees that each student has an equal chance of being selected. To make it less time-consuming and to avoid any bias, place all the students' names in a box and draw out the names required. After selecting ten students, divide them into two groups of five. One group will be the control group and the other will be the experimental group.
