Complete the sentence descriptive statistics deals with methods of ____

In Clauses , you learned that there are two types of clauses: Recall that independent clauses are complete sentences because they have a subject and verb and express a complete thought. Dependent clauses, in contrast, cannot stand alone because they do not express a complete thought—even though they have a subject and a verb. Independent and dependent clauses can be used in a number of ways to form the four basic types of sentences: Time to make their acquaintance.

Qualitative Data Analysis Methods. What is the first thing that comes to mind when we see data? The first instinct is to find patterns, connections, and relationships. We look at the data to find meaning in it. Similarly, in research, once data is collected, the next step is to get insights from it. For example, if a clothing brand is trying to identify the latest trends among young women, the brand will first reach out to young women and ask them questions relevant to the research objective.

After collecting this information, the brand will analyze that data to identify patterns — for example, it may discover that most young women would like to see more variety of jeans. Data analysis is how researchers go from a mass of data to meaningful insights. There are many different data analysis methods, depending on the type of research.

Here are a few methods you can use to analyze quantitative and qualitative data. The first stage of analyzing data is data preparation, where the aim is to convert raw data into something meaningful and readable. It includes four steps:. The purpose of data validation is to find out, as far as possible, whether the data collection was done as per the pre-set standards and without any bias. It is a four-step process, which includes…. To do this, researchers would need to pick a random sample of completed surveys and validate the collected data.

Note that this can be time-consuming for surveys with lots of responses. For example, imagine a survey with respondents split into 2 cities. The researcher can pick a sample of 20 random respondents from each city. After this, the researcher can reach out to them through email or phone and check their responses to a certain set of questions. Check out 18 data validations that will prevent bad data from slipping into your data set in the first place.

Typically, large data sets include errors. For example, respondents may fill fields incorrectly or skip them accidentally. To make sure that there are no such errors, the researcher should conduct basic data checks , check for outliers , and edit the raw research data to identify and clear out any data points that may hamper the accuracy of the results. For example, an error could be fields that were left empty by respondents.

While editing the data, it is important to make sure to remove or fill all the empty fields. Here are 4 methods to deal with missing data. This is one of the most important steps in data preparation. It refers to grouping and assigning values to responses from the survey. For example, if a researcher has interviewed 1, people and now wants to find the average age of the respondents, the researcher will create age buckets and categorize the age of each of the respondent as per these codes.

For example, respondents between years old would have their age coded as 0, as 1, as 2, etc. Then during analysis, the researcher can deal with simplified age brackets, rather than a massive range of individual ages. After these steps, the data is ready for analysis. The two most commonly used quantitative data analysis methods are descriptive statistics and inferential statistics.

Typically descriptive statistics also known as descriptive analysis is the first level of analysis. It helps researchers summarize the data and find patterns. A few commonly used descriptive statistics are:. Descriptive statistics provide absolute numbers. However, they do not explain the rationale or reasoning behind those numbers. For example, a percentage is a good way to show the gender distribution of respondents.

Descriptive statistics are most helpful when the research is limited to the sample and does not need to be generalized to a larger population. For example, if you are comparing the percentage of children vaccinated in two different villages, then descriptive statistics is enough. Since descriptive analysis is mostly used for analyzing single variable, it is often called univariate analysis. Often, researchers collect data on a sample of their population, then they generalize the results to the entire population or target group.

Inferential statistics are used to generalize results and make predictions about a larger population. These are complex analyses that show the relationship between several different variables, rather than describing a single variable. They are used when the researcher needs to go beyond absolute values and understand the relations between variables. The choice of inferential statistic completely depends upon the research objective.

Like in the case of descriptive statistics, it is best to identify the appropriate inferential statistic for your research questions. Since inferential statistics are used to determine the relationship between two or more variables, they are called bivariate analysis when limited to two variables or multivariate analysis when there are more than two variables. The above-stated methods are the most commonly used methods for data analysis.

However, other data analysis methods and metrics, such as standard deviation and variance, are also available. Qualitative data analysis works a little differently from quantitative data, primarily because qualitative data is made up of words, observations, images, and even symbols. Deriving absolute meaning from such data is nearly impossible; hence, it is mostly used for exploratory research.

While in quantitative research there is a clear distinction between the data preparation and data analysis stage, analysis for qualitative research often begins as soon as the data is available. One way is to use word-based methods , such as word repetitions. In this method, the researcher simply reads the text and identifies the words used most often. Another word-based technique is key words in context.

Here, the researcher tries to understand a concept by looking at the context in which it is used. For example, if researchers are trying to analyze the concept of depression among respondents, they can analyze the context of when the respondent has referred to depression. This could be while discussing mental health, family-related issues, etc. Another method of identifying patterns is called scrutiny-based techniques. One such method is the compare and contrast method , where a theme represents a way in which texts are similar or different from each other.

Other scrutiny-based methods to identify patterns or themes include looking for metaphors and analogies in the text, or looking for connectors in the form of words or phrases that indicate a relationship between different ideas or things. Did you collect your qualitative data right? Check out the 3 qualitative research methods you should know. Several methods are available to analyze qualitative data.

The most commonly used data analysis methods are:. These methods are the ones used most commonly. However, other data analysis methods, such as conversational analysis, are also available. Data analysis is perhaps the most important component of research. Weak analysis produces inaccurate results that not only hamper the authenticity of the research but also make the findings unusable.

Chapter 1. Introduction to Academic Writing

The first step in solving problems in public health and making evidence-based decisions is to collect accurate data and to describe, summarize, and present it in such a way that it can be used to address problems. Information consists of data elements or data points which represent the variables of interest. When dealing with public health problems the units of measurement are most often individual people, although if we were studying differences in medical practice across the US, the subjects, or units of measurement, might be hospitals. A population consists of all subjects of interest, in contrast to a sample , which is a subset of the population of interest. It is generally not possible to gather information on all members of a population of interest. Instead, we select a sample from the population of interest, and generalizations about the population are based on the assumption that the sample is representative of the population from which it was drawn.

Use ten intervals. The size of each interval is 5. This additional information may include the midpoint of each interval, the percentage of the numbers in the frequency column relative to the total frequencies, the cumulative frequency of successive summation of entries in the frequency column, and the percentage of the cumulative frequency. Example 3: In the frequency distribution for example 2 find a the midpoint of each interval; b the percentage of each frequency relative to the total frequencies; c the cumulative frequency; and d the percentage of cumulative frequency relative to the total frequencies. For example, the lowest interval contains the scores 56, 57, 58, 59, The frequency of the lowest interval is 2. The total number of measurements is Change the resulting decimal to a percent. This figure may also be found by adding the percentage of frequency of all groups from the lowest up to and including the given interval.
