MS 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.

After 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.

Versions 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)

Column
Chart
• Use this chart type to visually compare values across a few categories.
Bar Chart
• Use this chart type to visually compare values across a few categories when the chart shows
duration or the category text is long.
Line Chart
• Use this chart type to show trend over time (years, months, and days) or categories.
Pie Chart
• Use this chart type to show proportions of a whole. Use it when the total of your numbers is
100%.
Scatter Chart
• Use this chart type to show the relationship between sets of values.
Surface Chart
• Use this chart type to show trends in values across two dimensions in a continuous curve.
Area Chart
• Use this chart type to show trends over time (years, months, and days) or categories. Use it to
highlight the magnitude of change over time.
Pivot Chart
• Use Pivot Charts to graphically summarize data and explore complicated data.

your password to lock that sheet
• Now, your sheet is password protected.
• Again you can Unprotect your Worksheet by same step
©MRKS 48
- 51. Workbook Protection
Keep others from making structural changes to
your workbook, such as moving, deleting or
adding sheets.
Procedure:
• On the Ribbon, select the Review tab
• In the Changes group, click Protect Workbook.

value in an array or range of data.
IF
Check whether a condition is met, and returns one value
if TRUE, and another value if FALSE.
©MRKS 60
- 61. Some Basic Function
VAR

and text in the sample).
VARP
Calculates variance based on the entire population (ignores
logical values and text in the population).
STDEV
Estimates the standard deviation based on a sample (ignores
logical values and text in the 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-Test
©MRKS 79

- 88. Some Applications of MS Excel
Used 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.
