What is Descriptive Statistics?
Descriptive statistics is a term referring to the examination of data that portrays, shows, or sums up data in a significant way with the end goal that, for instance, patterns may arise out of the data. Descriptive statistics don't, in any case, permit us to cause ends past the data we have to investigate or arrive at resolutions with respect to any theories we may have made. They are basically an approach to explain our data. Descriptive statistics are vital since, supposing that we just introduced our raw data, it is difficult to envision what the data was appearing, particularly if there was a ton of it.
How does Descriptive Statistics work?
Descriptive statistics, hence, empowers us to introduce the data in a more significant manner, which permits a less complex translation of the data. For instance, on the off chance that we had the results of 100 bits of understudies' coursework, we might be keen on the general performance of those understudies. We would likewise be keen on the appropriation or spread of the marks. Descriptive statistics permit this to get this done.
Types and Examples:
Data can be described in many ways in stats, however, there are two popular methods described below:
Measures of central tendency:
These are methods of portraying the central position of a frequency distribution for a class of data. For this situation, the frequency distribution is just the distribution and pattern of numbers scored by the 100 understudies from the bottom to the top score. We can explain/portray this central position utilizing various statistics, including the mean, median, and mode.
Measures of spread:
These are methods of summing up a class of data by portraying how to spread out the scores are. For instance, the mean score of our 100 understudies perhaps 65 out of 100. Notwithstanding, not all understudies will have scored 65. Maybe, their scores will be spread out. Some will be lower and others higher. Measures of spread assist us with summing up how spread-out these scores are. To depict this spread, various statistics are accessible to us, including the reach, quartiles, absolute deviation, variance, and standard deviation.
