  2. Pivot table - Wikipedia

    en.wikipedia.org/wiki/Pivot_table

    Column labels are used to apply a filter to one or more columns that have to be shown in the pivot table. For instance if the "Salesperson" field is dragged to this area, then the table constructed will have values from the column "Sales Person", i.e., one will have a number of columns equal to the number of "Salesperson". There will also be ...

  3. Frequency (statistics) - Wikipedia

    en.wikipedia.org/wiki/Frequency_(statistics)

    Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample. This is an example of a univariate (=single variable) frequency table. The frequency of each response to a survey question is depicted.

  4. Position weight matrix - Wikipedia

    en.wikipedia.org/wiki/Position_weight_matrix

    A PWM has one row for each symbol of the alphabet (4 rows for nucleotides in DNA sequences or 20 rows for amino acids in protein sequences) and one column for each position in the pattern. In the first step in constructing a PWM, a basic position frequency matrix (PFM) is created by counting the occurrences of each nucleotide at each position.

  5. Check sheet - Wikipedia

    en.wikipedia.org/wiki/Check_sheet

    A single column listing each defect category; One or more columns in which the observations for different machines, materials, methods, operators are to be recorded; Note that the defect categories and how process outputs are to be placed into these categories must be agreed to and spelled out in advance of constructing the check sheet.

  6. Bar chart - Wikipedia

    en.wikipedia.org/wiki/Bar_chart

    The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart and has been identified as the prototype of charts. [1] A bar graph shows comparisons among discrete categories. One axis of the chart shows the specific categories being compared, and the other axis represents a measured value.

  7. Document-term matrix - Wikipedia

    en.wikipedia.org/wiki/Document-term_matrix

    which shows which documents contain which terms and how many times they appear. Note that, unlike representing a document as just a token-count list, the document-term matrix includes all terms in the corpus (i.e. the corpus vocabulary), which is why there are zero-counts for terms in the corpus which do not also occur in a specific document.

  8. Decision table - Wikipedia

    en.wikipedia.org/wiki/Decision_table

    Decision tables are a concise visual representation for specifying which actions to perform depending on given conditions. Decision table is the term used for a Control table or State-transition table in the field of Business process modeling; they are usually formatted as the transpose of the way they are formatted in Software engineering.

  9. Pareto principle - Wikipedia

    en.wikipedia.org/wiki/Pareto_principle

    Form a frequency of occurrences as a percentage; Arrange the rows in decreasing order of importance of the causes (i.e., the most important cause first) Add a cumulative percentage column to the table, then plot the information; Plot (#1) a curve with causes on x- and cumulative percentage on y-axis
