The list may be protected by privacy policies or require a lengthy process to attain permissions. If we wanted to look at the differences in male and female students, this would mean choosing gender as the , but it could similarly involve choosing students from different subjects (e. As a result, the stratified random sample provides us with a , stratified random sampling allows us to make statistical conclusions from the data collected that will be considered to be valid. Indeed, it will be more complex and time consuming to prepare this list compared with many lists will not be in the public domain and their purchase may be expensive at least in terms of the research funds of a typical undergraduate or masters level dissertation student. We need to ensure that the number of units selected for the sample from each stratum is to the number of males and females in the population. Clearly, a student could only be classified as either male or female. If this was the case, we would want to ensure that the sample we selected had a proportional number of male and female students. Therefore, the stratified random sample involves dividing the population into for example, imagine we were interested in comparing the differences in career goals between male and female students at the university of bath. There may be no single list detailing the population you are interested in. Many lists will not be in the public domain and their purchase may be expensive at least in terms of the research funds of a typical undergraduate or masters level dissertation student. Because of the greater precision of a stratified random sample compared with a simple random sample, it may be possible to use a smaller sample, which saves time and money. These 10,000 students are our ) of students from this population of 10,000 students, we could choose to use a ) within the population. This number was chosen because it reflects the limit of our budget and the time we have to distribute our questionnaire to students. Assuming that your list has all the contact details of potential participants in the first instance, managing the different ways (postal, telephone, email) that may be required to contact your sample may be challenging, not forgetting the fact that your sample may also be geographical scattered. As an undergraduate and master?s level dissertation student, you may simply not have sufficient time to do this. No student could fit into both categories (ignoring transgender issues). This is known as , where the sample size of each of the stratum is not proportionate to the population size of the same stratum). We explain how this is achieved in the next section in our example, the population is the 10,000 students at the university of bath. If we were only interested in female university students, for example, we would exclude all males in creating our sampling frame, which would be much less than 10,000 students. However, we could have also determined the sample size we needed using a sample size calculation, which is a particularly useful statistical tool.

We keep doing this until we have all 200 students that we want in our sample. Since the strata must be mutually exclusive and collectively exclusive, this means that we would need to sample four strata from the population undergraduate males, undergraduate females, graduate males, and graduate females. If we do the same for male students, we get 40 students (i. Because of the greater precision of a stratified random sample compared with a simple random sample, it may be possible to use a smaller sample, which saves time and money. Imagine that a researcher wants to understand more about the career goals of students at a single university. Assuming that your list has all the contact details of potential participants in the first instance, managing the different ways (e. The population is expressed as n. If our desired was around 200 students, each of these students would subsequently be sent a questionnaire to complete (imagining we choose to collect our data using a questionnaire). If we were only interested in female university students, for example, we would exclude all males in creating our sampling frame, which would be much less than 10,000 students. These random numbers can either be found using random number tables or a computer program that generates these numbers for you. If you were actually carrying out this research, you would most likely have had to receive permission from student records (or another department in the university) to view a list of all students studying at the university. As a result, the stratified random sample provides us with a , stratified random sampling allows us to make statistical conclusions from the data collected that will be considered to be valid. In terms of human populations (as opposed to other types of populations see the article ), some of these populations will be expensive and time consuming to contact, even where a list is available.

We explain how this is achieved in the next section in our example, the population is the 10,000 students at the university of bath. Furthermore, where the samples are the same size, a stratified random sample can provide greater precision than a simple random sample. This will increase overall sample size required for the research, which can increase costs and time to carry out the research. You can read about this later in the article under.

This is a major advantage because such generalisations are more likely to be considered to have attaining a complete list of the population can be difficult for a number of reasons even if a list is readily available, it may be challenging to gain access to that list. ). If this was the case, we would want to ensure that the sample we selected had a proportional number of male and female students.

Relative to the simple random sample, the selection of units using a stratified procedure can be viewed as superior because it improves the potential for the units to be more evenly spread over the population. If we wanted to look at the differences in male and female students, this would mean choosing gender as the , but it could similarly involve choosing students from different subjects (e.
