Descriptive Analysis: How-To, Types, Examples

Published on July 9, by Pritha Bhandari. Revised on February 15, Descriptive statistics summarize and organize characteristics of a data set. A data set is a collection of responses or observations from a sample or entire population, explain descriptive.

In quantitative researchafter collecting data, the first step of statistical analysis is to describe characteristics of the responses, such as the average of one variable e. The next step is inferential statisticswhich help you decide whether your data confirms or refutes your hypothesis and whether it is generalizable to a larger population.

Table of contents Types of descriptive statistics Frequency distribution Measures of central tendency Measures of variability Univariate descriptive statistics Bivariate descriptive statistics Frequently asked questions about descriptive statistics.

You can apply these to assess only one variable at a time, in univariate analysis, or to compare two or more, in bivariate and multivariate analysis. Your data set is the collection of responses to the survey.

Now you can use descriptive statistics to find out the overall frequency of each activity distributionthe averages for each activity central tendencyand the spread of responses for each activity variability. Frequency distribution A data set is made up of a distribution of values, or scores. In tables or graphs, explain descriptive, you can summarize the frequency of every possible value of a variable in numbers or percentages.

From this table, you can see that more women than men took part in the study. In a grouped frequency distribution, you can group numerical response values and add up the number of responses for each group. You can also convert each of these numbers to percentages. From this table, explain descriptive, you can see that most people visited the library between 5 and 16 times in the past year.

See an example. Measures of central tendency estimate the center, or average, of a data set. The meanmedian and mode are 3 ways of finding the average. Here we will demonstrate how to calculate the mean, median, and mode using the first 6 responses of our survey.

The explain descriptiveor Mexplain descriptive, is the most commonly used method for finding the average.

To find the mean, simply add up all response values and divide the sum by the total number of responses. The total number of responses or observations is called N.

To find the median, explain descriptive, order each response value from the explain descriptive to the biggest. Then, the median is the number in the explain descriptive. If there are two numbers in the middle, find their mean.

The mode is the simply the most popular or most frequent response value, explain descriptive. A data set can have no mode, one mode, or more than one mode.

To find the mode, order your data set from lowest to highest and find the response that occurs most frequently. Measures of variability give you explain descriptive sense of how explain descriptive out the response values are. The range, standard deviation and variance each reflect different aspects of spread.

The range gives you an idea of how far apart the most extreme response scores are. To find the rangesimply subtract the lowest value from the highest value.

It tells you, on average, how far each explain descriptive lies from the mean. The larger the standard deviation, the more variable the data set is. Variance The variance is the average of squared deviations from the mean.

Variance reflects the degree of spread in the data set. The more spread the data, the larger the variance is in relation to the mean. To find the variance, simply square the standard deviation. The symbol for variance is s 2. Programs like SPSS and Excel can be used to easily explain descriptive these. Likewise, while the range is sensitive to extreme values, explain descriptive, you should also consider the standard deviation and variance to get easily comparable measures of spread.

In bivariate analysis, you simultaneously study the frequency and variability of two variables to see if they vary together. You can also compare the central tendency of the two variables before performing further statistical tests.

In a contingency table, each cell represents the intersection of two variables. Usually, an independent variable e, explain descriptive. Interpreting a contingency table is easier when the raw data is converted to percentages. Percentages make each row comparable to the other by making it seem as if each group had only observations or participants.

When creating a percentage-based contingency table, you add the N for each independent variable on the end. From this table, it is explain descriptive clear that similar proportions of men and women go to the library over 17 times a year. Additionally, explain descriptive, men most commonly went to the library between 5 and 8 times, while for women, this number was between 13 and A scatter plot explain descriptive a chart that shows you the relationship between two or three variables.

In a scatter plot, you plot one variable along the x-axis and another one along the y-axis. Each data point is represented by a point in the chart. From your scatter plot, you see that as the number of movies seen at movie theaters decreases, the number of visits to the library increases.

Based on your visual assessment of a possible linear relationship, you perform further tests of correlation and regression. Descriptive statistics summarize the characteristics of a data set. Inferential statistics allow you to test a hypothesis or assess whether your data is generalizable to the broader population. Explain descriptive 3 main types of descriptive statistics concern the frequency distribution, explain descriptive, central tendency, and variability of a dataset.

What are the 3 main types of descriptive statistics? Distribution refers to the frequencies of different responses, explain descriptive. Measures of central tendency give you the average for each response. Measures of variability show explain descriptive the spread or dispersion of your dataset. Univariate statistics summarize only one variable at a time, explain descriptive.

Bivariate statistics compare two variables. Multivariate explain descriptive compare more than two variables. Is this article helpful?

As an interdisciplinary researcher, she enjoys writing articles explaining tricky research concepts for students and academics.
