About MS EXCELMRKS2

MS EXCELMS Excel is a spreadsheet program that enables us to store and manipulate data in a tabular form.Spreadsheet also called worksheets, which are made up of columns & rows.Rows are numbered numerically and columns are labelled alphabetically.MRKS3

MS EXCELAfter Zth column, the column are labelled as AA, AB, AC, and so on. Again after the AZth column, the columns are labelled as BA, BB, BC, and so on.The intersection of rows & column is called a cell, which can store text, number data, and mathematical formulas.Each spreadsheet contains 10,48,576 rows & 16,384 column that make 1048576*16384 = 17179869184 cells in MS Excel 2013.MS Excel contains a group of worksheets, which is known as a workbook.MRKS4

Rows & Column in Various versionsMRKSVersions of Excel up to 7.0 (1995 Excel for Windows 95) had a limitation in the size of their data sets of 16K (214= 16384) rows.Versions 8.0 (1997 Excel 97) through 11.0 (Excel 2003) could handle 64K (216= 65536) rows and 256 columns (28as label 'IV').Version 12.0 (Excel 2007) can handle 1M (220= 1048576) rows, and 16384 (214as label 'XFD') columns.Wikipedia5

Use of Some FunctionsMRKS58

Some Basic FunctionSUMAutomatically add it up. Your total will appear after the selected cells.AVERAGEReturns the average (arithmetic mean) of its arguments, which can be number or references that contain numbers.COUNTCounts the number of cells in a range that contain numbers.MEDIANReturns the median, or the number in the middle of the set of given numbers.MRKS59

Some Basic FunctionMRKSMAXReturns the largest value in a set of values. Ignores logical values and text.MINReturns the smallest value in a set of values. Ignore logical values and text.MODEReturns the most frequency occurring, or repetitive, value in an array or range of data.IFCheck whether a condition is met, and returns one value if TRUE, and another value if FALSE.60

Some Basic FunctionMRKSVAREstimates variance based on a sample (ignore logical values and text in the sample).VARPCalculates variance based on the entire population (ignores logical values and text in the population).STDEVEstimates the standard deviation based on a sample (ignores logical values and text in the sample).STDEVPCalculates standard deviation based on the entire population given as arguments (ignore logical values and text).61

Inserting a functionMRKSThere are two ways to insert a function.Select a cell,Go to Formulas Ribbon,Select function categories from Function LibraryInsert the functionSelect the range inside the parentheses.Select a cellInsert a function manually after =.Select range inside the parentheses.Note: In case 2, you have to know the abbreviations used for functions.63

E.g., Inserting a T-Test functionReturns the probability associated with a Students t-Test.Procedure:Select the cell.Insert the ttest function after the = inside the ().Give the range for array1 & array2 separating by (,)Input the tail value i.e., 1 or 2.Input the type i.e., 1, 2, or 3.Lastly close the function inside the parenthesis.MRKS64

MRKS65

E.g., Inserting a Correlation functionReturn the correlation coefficient between two data sets.Procedure:Select a cell.Insert correl function after = inside the ().Give the range for array1 & array2 separating by (,).Lastly close the function inside the parenthesis.MRKS66

Inserting Functions from Data AnalysisMRKS71

CorrelationMRKSThe CORREL functions calculate the correlation coefficient between two measurement variables when measurements on each variable are observed for each of N subjects. It provides an output table, a correlation matrix, that shows the value of CORREL applied to each possible pair of measurement variables.72

CorrelationMRKSProcedure:Click the File tab, click Data Analysis Tool.A dialogue box will appear tha contain names of some functions.Select Correlation from the box, then OK.Another dialogue box appear.Give Input range & Output range as well as specify the matrix inserted row-wise or column wise.73

t-Test: Two-Sample Assuming Unequal VariancesMRKSThis analysis tool performs a two-sample student's t-Test. This t-Test form assumes that the two data sets came from distributions with unequal variances. It is referred to as a heteroscedastic t-Test79

t-Test: Two-Sample Assuming Unequal VariancesMRKSProcedure:Click the File tab, click Data Analysis Tool.A dialogue box will appear tha contain names of some functions.Select t-Test: Two-Sample Assuming Unequal Variances from the box, then OK.Another dialogue box appear.Give Input range i.e., variable1 and variable2 & Output range. Then, click OK.80

Some Applications of MS ExcelMRKSUsed for data analysis as it has financial and statistical function.Storing data in systematic way. Like one Excel file for each day.Making invoices, timesheet, Trackers etc.Creating charts for presentation which further can be moved to presentation software like Power Point.Used for cleaning data like removing duplicate reports, filtering out specific records etc.Also used for coding, we can create a formulated sheet through which we can get automatically results.88
