Difference Between Descriptive and Inferential Statistics

➦ Difference Between Descriptive and Inferential Statistics: Statistics is the art of collecting, analyzing, presenting, and interpreting data. Statistics is sub-divided into two categories:

  • Descriptive Statistics
  • Inferential Statistics

Descriptive Statistics

➦ Descriptive statistics serves as a method for succinctly presenting and summarizing data sets.

➦ It functions as a tool to organize and articulate numerical information meaningfully. Consider a scenario where numerical values, such as test scores, are involved.

➦ Descriptive statistics facilitates the representation of these figures through measures such as the mean, median, and mode, offering insights into the central tendencies within the data.

➦ Furthermore, it encompasses measures of variability, including range and standard deviation, elucidating the dispersion of the data.

➦ In essence, descriptive statistics provides a comprehensive portrayal of the data, enhancing our capacity to comprehend and interpret its characteristics.

Inferential Statistics

➦ Inferential statistics addresses scenarios wherein acquiring information about an entire population is unfeasible, necessitating the extraction of insights from a representative sample.

➦ This branch of statistics allows for the formulation of predictions or inferences about a population based on a subset of data.

➦ Analogous to selecting and analyzing a sample of marbles from a larger collection, inferential statistics enables reasoned conclusions about the broader population.

➦ Techniques such as hypothesis testing, confidence intervals, and regression analysis are integral components of inferential statistics.

➦ In summary, inferential statistics facilitates informed conjectures about a larger group without the impracticality of scrutinizing each individual element.

Difference Between Descriptive and Inferential Statistics

Descriptive Statistics Inferential Statistics
Descriptive Statistics gives description or we can say it focuses on the collection, presentation, and characterization about a sample. Inferential Statistics helps to predict and estimate the possible characteristics of the population from the sample data drawn from the population.
Descriptive Statistics only describes certain characteristics of the data. Inferential Statistics deeply analyzes statistical data and observations.
Descriptive Statistics helps in dealing with the central tendency and spread of the frequency distribution. Inferential Statistics helps in studying details about the hypothesis test and confidence level.
Descriptive Statistics can be measured either numerically (mean, median, mode) or graphically. Inferential Statistics cannot be always measured in exact numbers.
Descriptive Statistics helps to produce error-free results as it deals with the small population. Inferential Statistics may not produce error-free results as it takes the whole population for drawing conclusion.
Drawing conclusions in descriptive statistics is limited within the given data i.e. we cannot make conclusions beyond the given data. Drawing conclusions in Inferential statistics is unlimited i.e. the educated predictions and guesses can be made on the basis of the parameters of the given population.
Examples:

  •  Information in newspapers, magazines, company reports, etc.
  •  Frequency of the variables.
  •  The population of the particular country.
Examples:

  •  Grades or percentile of the scores.
  • The average score in cricket.
  • Prediction about cancer by the doctor.
