There are three major types of estimates of central tendency: Mean Median Mode The Mean or average is probably the most commonly used method of describing central tendency.

To compute the mean all you do is add up all the values and divide by the number of values. For example, the mean or average quiz score is determined by summing all the scores and dividing by the number of students taking the exam.

The Median is the score found at the exact middle of the set of values. One way to compute the median is to list all scores in numerical order, and then locate the score in the center of the sample.

For example, if there are scores in the list, score would be the median. If we order the 8 scores shown above, we would get: 15,15,15,20,20,21,25,36 There are 8 scores and score 4 and 5 represent the halfway point.

Since both of these scores are 20, the median is If the two middle scores had different values, you would have to interpolate to determine the median. The mode is the most frequently occurring value in the set of scores.

As with psychology itself, statistical analysis within psychology began as a philosophy Goodwin, Descriptive statistics describe the features of the data collected. Descriptive statistics provides information focused on an immediate group of data. Statistical analysis dream wedding descriptive essay also involve much time and effort, and therefore an understanding of the proper structure of descriptive and inferential statistics is crucial before expensive investments of time and resources are wasted because data is not collected using proper methods.

There are three major characteristics of a single variable that we tend to look at: the distribution the central tendency the dispersion In most situations, we would describe all three of these characteristics for each of the variables in our study.

Inferential Statistics Inferential statistics are produced through complex mathematical calculations that allow scientists to infer trends about a larger population based on a study of a sample taken from it. It is usually impossible to examine each member of the population individually.

Social Research Methods - Knowledge Base - Descriptive Statistics

There are two major divisions of inferential statistics: A confidence interval gives a range of values for an unknown parameter of the population by measuring a statistical sample. This is expressed in terms of an interval and the degree of confidence that the parameter is within the interval.

Teenagers are more likely to engage in tech talk compared to other age groups. For instance, we use inferential statistics to try to infer from the sample data what the population might think. Or, we use inferential statistics to make judgments of the probability that an observed difference between groups is a dependable one or one that might have happened by chance in this study. Thus, we use inferential statistics to make inferences from our data to more general conditions; we use descriptive statistics simply to describe what's going on in our data. Descriptive Statistics are used to present quantitative descriptions in a manageable form. In a research study we may have lots of measures. Or we may measure a large number of people on any measure. Descriptive statistics help us to simplify large amounts of data in a sensible way. Each descriptive statistic reduces lots of data into a simpler summary. For instance, consider a simple number used to summarize how well a batter is performing in baseball, the batting average. This single number is simply the number of hits divided by the number of times at bat reported to three significant digits. A batter who is hitting. One batting. The single number describes a large number of discrete events. This single number describes the general performance of a student across a potentially wide range of course experiences. Every time you try to describe a large set of observations with a single indicator you run the risk of distorting the original data or losing important detail. A mean tells scientists the mathematical average of all of a data set, such as the average age at first marriage; the median represents the middle of the data distribution, like the age that sits in the middle of the range of ages at which people first marry; and, the mode might be the most common age at which people first marry. Inferential Statistics Inferential statistics are produced through complex mathematical calculations that allow scientists to infer trends about a larger population based on a study of a sample taken from it. It is usually impossible to examine each member of the population individually. There are two major divisions of inferential statistics: A confidence interval gives a range of values for an unknown parameter of the population by measuring a statistical sample. Both descriptive and inferential statistics can help Social Scientists get a snapshot of either a certain population or sample of a population. Why does it matter?
