Shape(s) of distribution (in statistics) Explanation: http://www.phys.ubbcluj.ro/~dana.maniu/BIOSTAT/C2.pdf “ASPECTUL simetric al distribuției....” http://sorana.academicdirect.ro/pages/doc/MV2012/MVRom04.pdf “În general are ASPECTUL de clopot, dar deoarece este asociată unui volum de eşantion mic prezintă o variabilitate mai mare …” https://mathbitsnotebook.com/Algebra1/StatisticsData/STShape... “Shapes of Distributions” “When graphed, the data in a set is arranged to show how the points are distributed throughout the set. These distributions show the spread (dispersion, variability, scatter) of the data. The spread may be stretched (covering a wider range) or squeezed (covering a narrower range). The shape of a distribution is described by its number of peaks and by its possession of symmetry, its tendency to skew, or its uniformity. (Distributions that are skewed have more points plotted on one side of the graph than on the other.)” |

(Descriptive and Inferential) aspects in Statistics Explanation: https://people.math.umass.edu/~jeneral/stat240/handout1.pdf The three main aspects of statistics:1)Design: Designing the process of data collection (Identify population, what kind and how much data needed, how to collect a sample) 2) Description:The methods of summarizing/describing data.3) Inference:Infer “general rules” about a population from a sample. Două metodologii statistice principale sunt utilizate în analiza datelor: statistici descriptive, care sintetizează datele dintr-un eșantion folosind indici cum ar fi media sau abaterea standard, și statistici inferențiale care trag concluzii din datele care sunt supuse unor variații aleatorii (precum erori de observație, variație de eșantionare, .... https://businessdegrees.uab.edu/blog/descriptive-statistics-... https://www.statisticshowto.datasciencecentral.com/inferenti... În Statistică, putem vorbi de un aspect DESCRIPTIV și unul INDUCTIV (sau INFERENȚIAL) -------------------------------------------------- Note added at 6 hrs (2020-02-28 15:15:49 GMT) -------------------------------------------------- https://explorable.com/branches-of-statistics Inferential statistics, as the name suggests, involves drawing the right conclusions from the statistical analysis that has been performed using descriptive statistics. In the end, it is the inferences that make studies important and this aspect is dealt with in inferential statistics. |
