Excel can create a visual timeline chart and help you map out a project schedule and project phases. Specifically, you can create a Gantt chart, which is a popular tool for project management because it maps out tasks based on how long they'll take, when they start, and when they finish.

1. OVERVIEWS OF STATISTICS WITH EXCEL
PREPARED BY- KRISHNA CHOUDHARY
PRESENTATION

2. STATISTICS INFORMATION
We can define statistics is a science in which we collect the data,
arrange it and by the analysis and interpretation of this the
organization make the decision.
. And data is the important tool of any organization.
. Data are divided in two parts 1. Quantitative data
2. Qualitative data
- by the uses of various mathematical function and various other tool
in excel we can analyze the data and we can find something valuable
in large data

3. STEM AND LEAF
-Stem-and-leaf plots are a method for showing the frequency with which certain classes of values
occur.
-You could make a frequency distribution table or a histogram for the values, or you can use a stem-
and-leaf plot and let the numbers themselves to show pretty much the same information.we can make
stem leam using manual calculation or either using REPT formula in excel.

5. FREQUENCY DISTRIBUTION
-A frequency distribution provides a visual representation for the distribution of
observations within a particular test. Analysts often use frequency distribution to
visualize or illustrate tlhe data collected in a sample.
- we have taken some data lets consider it is the price of 15 bike(rupees) given in
table.
price of bike in
rupees
641773555345546
324553432144224
345233333293753
353535323433664
352233544644456

6. DETERMINATION OF CLASS AND
WIDTH
-to determine the number of classes (k) is the “2 to the k rule.”
such that 2k > n.
Here we have n=15 so 2^4=16
-for the determination of the width we have the formula
i  (H-L)/k where i is the class interval, H is the highest observed
value, L is the lowest observed value, and k is the number of
classes.
So the interval we got 15324.5 round
Up the value to 15325

11. PERCENTILE
A percentile is a measure at which that percentage of the total values are the same
as or below that measure. For example, 90% of the data values lie below the 90th
percentile, whereas 10% of the data values lie below the 10th percentile.
Formula:-(n+1)p/100 where p= percentile and n= total number
Eg. We have 6,9,23,25,35,36,57,74,calculate the 50th percentile
Solution here total no. n=8 p = 50 put these value in the formula
So we get (8+1)50/100 = 4.5 so the 50th percentile is 25.5
By the above way we can find any percentile

12. QUARTILE- Quartile are the percentage point that break down the data set into
quarter like 1quater 2nd quarter 3rd quarter, 4th quarter
1quartile= 25% percentile
2nd quartile= 50% percentile
3rd quartile= 75% percentile like wise
Formula= 1st quartile= ¼(n+1)th term
3nd quartile= 3/4(n+1)th term like wise.
Eg .2,3,5,6,8,9 find the 1st and 3rd quartile of this data
Solution
Here n= 6 so 3rd quartile ¾(6+1)th term= 5.25th term so it will be
8.25
1st quartile= ¼(6+1)th term= 1.75th term so it will be 2.75

13. QUATILE RANGE
Quartile range is the difference between 3rd-1st quartile
So we have 3rd quartile =8.25
And 1st quartile= 2.75 so inter quartile range will be
8.25-2.75=5.5

14. VARIANCE AND STANDARD DEVIATION
-The variance (symbolized by S2) and standard deviation (the square
root of the variance, symbolized by S) are the most commonly used
measures of spread.
Variance formulation it is for the population for
samle put in place of n (n-1) in dominator
- standard deviation is the square root of variance so the formula will
be
This for applied for the discrete types of data for the continuous data
other formula is utilize

34. DATA AND DATA BASE
Sumif:-The SUMIF function returns the sum of cells in a range that meet a single
condition. The first argument is the range to apply criteria to, the second argument is the
criteria, and the last argument is the range containing values to sum.
I utilize this formula in excel

35. SUMIFS
 SUMIFS is a function to sum cells that meet multiple
criteria. SUMIFS can be used to sum values when adjacent cells meet
criteria based on dates, numbers, and text. SUMIFS supports logical
operators (>,<,<>,=) and wildcards (*,?) for partial matching.
