Q3. What are the 6 types of statistics?<\/a><\/li><\/ul><\/li><\/ul><\/nav><\/div>\n\n\n\n\nStatistics is the study of the analysis, presentation, collection, interpretation, organization, and large data presentation. It can be defined as a function of the given data. <\/p>\n\n\n\n
That is why statistics are combined with classifying, presenting, collecting, and arranging the numerical information in some meaningful manner. <\/p>\n\n\n\n
It also facilitates interpreting several outcomes from the given data and estimating all possibilities for the upcoming applications. <\/p>\n\n\n\n
With the help of statistics, one can find several measures of central data as well as the deviations of dissimilar values from the main values.<\/p>\n\n\n\n
Before proceeding to the advanced terminologies of statistics, let’s check whether you understand basic terminologies of statistics, i.e., population <\/em>and sample.<\/em><\/p>\n\n\n\n<\/span>Take A Test Of Your Knowledge About Population And Sample!!!<\/strong><\/span><\/h2>\n\n\n\nSelect the population and sample from the given statements:<\/p>\n\n\n\n

The opinion poll is assumed to express the opinions of the voters in the whole country.<\/strong><\/span><\/h4>\n\n\n\nSample<\/strong>: Samples of 1,500-2,500 voters.

An automobile company liked to understand whether more than 60% of the American drivers own at least a private vehicle or not. The manufacturer surveyed 15,000 private vehicle drivers over America.<\/strong><\/span><\/h4>\n\n\n\nSample: <\/strong>15,000 private vehicle drivers who have been surveyed.

Suppose you are assigned to compute the average grade point scored in a subject at school. It would be better to select the students’ sample who visit the school. The collected data from a given samples could be the average grade point scored by the students.<\/strong><\/span><\/h4>\n\n\n\nSample<\/strong>: Suppose the sample of 50 students.

Houston city requires to understand whether the city’s annual house income is greater than the national average or not. The city’s statisticians gather data from 2,000 households.<\/strong><\/span><\/h4>\n\n\n\nSample: <\/strong>2,000 households who are being examined.

Categorical (qualitative)<\/strong><\/span><\/h3>\n\n\n\n\nOrdinal: <\/strong>It has ordered qualitative variables in the given data such as sometimes, always, never, frequently, and much more. <\/li>\n\n\n\nNominal: <\/strong>It has unordered qualitative variables in the collected data such as gender, hair color, and much more.<\/li>\n<\/ul>\n\n\n\n<\/span>2. Quantitative data<\/strong><\/span><\/h3>\n\n\n\n\nContinuous:<\/strong> It has numerical variables with an infinite number of collected values, such as height and much more.<\/li>\n\n\n\nDiscrete:<\/strong> It consists of numeric variables that are easily counted, such as the number of bacteria and others.<\/li>\n<\/ul>\n\n\n\n<\/span>3. Visualizing data<\/strong><\/span><\/h3>\n\n\n\n\nTables:<\/strong> It has numeric conclusions of the percent values, frequencies, summary statistics, and much more.<\/li>\n\n\n\nGraphs: <\/strong>It is used to represent the different numeric data in the form of:<\/li>\n<\/ul>\n\n\n\n\nScatterplot: <\/strong>It is used to plot the two numeric variables.<\/li>\n\n\n\nHistogram: <\/strong>It can represent the data in a bar graph view of frequencies.<\/li>\n\n\n\nBoxplot: <\/strong>It can present the median, mean, range, and quartiles of the collected data.
