STATISTICS FOR MANAGEMENT – SET (1) 1) WHY IT IS NECESSARY TO SUMMARISE DATA? EXPLAIN THE APPROACHES AVAILABLE TO SUMMARIZE THE DATA DISTRIBUTIONS? ➢ Graphical representation is a good way to represent summarised data. However, graphs provide us only an overview and thus may not be used for further analysis. Hence, we use summary statistics like computing averages. to analyse the data. Mass data, which is collected, classified, tabulated and presented systematically, is analysed further to bring its size to a single representative figure. This single figure is the measure which can be found at central part of the range of all values. It is the one which represents the entire data set. Hence, this is called the measure of …show more content…
When there are many tables in an analysis, then table numbers are helpful in identifying the tables. ii) TITLE: It indicates the scope and the nature of contents in concise form. In other words, title of a table gives information about the data contained in the body of the table. It should not be lengthy. iii) CAPTIONS: Captions are the headings and subheadings describing the data present in the columns. iv) STUBS: These are the headings and subheadings of rows. v) BODY OF THE TABLE: It contains numerical information vi) RULING AND SPACING: It separates columns and rows. However, totals are separated from main body by thick lines. vii) HEAD NOTE: It is given below the title of the table to indicate the units of measurement of the data and is enclosed in brackets. viii) SOURCE NOTE: It indicates the source from which data is taken. The source note related to table is placed at the bottom on the left hand corner. TABLE 1 - % OF DISTRIBUTION OF POPULATION |Marital Status |Age/Sex |LITERATE |ILLITERATE | |
Data and statistics is able to be collected through a number of different ways to gather information, the majority of people have taken part
Each statistic in the descriptive form lowers the quantity of data into a much simpler summary.
When a new column is added to a spreadsheet it is added to the _____ of the selected column. (Unit 5)
The lab uses the measurements of a wooden dowel in length and diameter to collect data in order to interpret data in report form. The data is used to produce statistical data and how to correctly present it. A ruler and micrometer were used to measure the dimensions. Spreadsheets are then constructed in order to generate standard deviation, mean, median, mode, frequency, as well as variation of length, diameter, volume, and cross sectional area of the
In this activity you will collect data and then perform statistical analyses to determine measures of central tendency and variation of the data. You will also represent
- Tables are useful in showing relationships and making comparisons. They should have title, row, column headings, population, source and explanations.
15. A rectangular range of cells with headings to describe the cells' contents is referred to as a
Descriptive statistics are digits that are used to summarize and describe a given range of data (Klenke, 2008). Basic descriptive data includes, mean, median, mode, variance and standard deviation. The data can be rearranged in an ascending order as follows:
Unique Column and Table Names: A column name within the table is unique because it is referenced by its table name. RDBMS does not restrict other tables to use same column names because they are identified by their table. Similarly table names within a database needs to be
Table headers is a row at the top of a table that helps you identify what is in the rows below each of the headers. For example, Name, date of Birth, and phone numbers on a table of contact
For example, the “Mining” table above means to show the performance of mining segment at 2013, 2014 and 2015, but audiences can’t receive the same information by just reading the title “Mining”. The third line of the “Mining table writes “(in millions of USD…)”, but many other financial tables have a simple version “(in $ millions)”. Thus, it can apply that your company didn’t apply the same style manual for making these financial
The header section contains meta-information lines, each one starts with the characters “##”, and a header line starting with the character “#” representing the first 8 fixed column names present in the data section. The "FORMAT" onwards are optional and are included to encapsulate per-sample/genome genotype data.
information in the analysis. The Appendix to this teaching note contains a discussion of these
In terms of independent variables, by referring to the Appendix, figure 1 reveals the summary of the sample; it also
The data thus collected were classified according to the categories, counting sheets & the summary tables were prepared.
