Microsoft Excel Tutorial p value

p-value in excel    

microsoft excel p value tutorial ms excel tutorial. excel tutorial for beginners  critical values hypothesis testing p value statics p value explained

Calculate the two-tailed inverse of Student's t distribution. The Advanced Excel TINV function calculates the inverse of the two-tailed Student T distribution, which is a continuous probability distribution often used to test hypotheses against small samples of data.

Uses of p value

The advanced excel tinv function is classified into statistical functions. It will calculate the t distribution of the left tail pupil. The student's t distribution is a continuous probability distribution that is often used to test hypotheses about small data sets of samples. As a financial analyst, the TINV function is used in the risk analysis of a portfolio, in particular the risk or return ratio of a portfolio. The function is often used when the sample size is smaller.

p value

 

Syntax of p-value

=TINV( probability, degrees_freedom )

 

Challenges of  p value

A.  If deg_freedom is not an integer, it is truncated.

B.  #NUM! error occurs when the given probability is less than or equal to zero or is greater than one. The given deg_freedom is less than 1.

C.  #VALUE! error occurs when one or both of the supplied arguments are non-numeric.

student t distribution 

Student t distribution formula in advanced excel

Find the percentage points (probability) for the 

Student t distribution where a numerical value 

(x) is a calculated value of t for which the 

percentage points are to be calculated. The 

t-distribution is used in the hypothesis test of 

small sample data sets. Use this function in 

place of a table of critical values ​​for the t 

distribution. The DIST function calculates the 

Student's T distribution, which is a continuous

 probability distribution often used to test 

hypotheses against small sample data sets. 

Returns the probability of percentage points 

for the t distribution.

Syntax of Student t distribution formula

TDIST(x, degrees_freedom, tails)

Challenges to use Student t distribution formula

 If "x" is not numeric, then #VALUE! is returned.

 If "degrees_freedom" is not an integer, it is truncated.

 If "degrees_freedom" < 1, then #NUM! is returned.

 If "degrees_freedom" is not numeric, then #VALUE! is returned.

 If "tails" is not an integer, it is truncated.

 If "tails" = 1, then the one-tailed distribution is used.

 If "tails" = 2, then the two-tailed distribution is used.

 If "tails" is any value other than 1 or 2, then #NUM! is returned.

 If "tails" is not numeric, then #VALUE! is returned. 

 

Advanced Excel Steyx Formula

Advanced Excel Steyx Formula

The Excel STEYX function finds the standard error of the predicted y-value for each x in the regression.

Description of Steyx Formula:

The standard error is a measure of the amount of error in the prediction of y for an individual x. The STEYX (known_y's, known_x's) function returns the standard error of Y given X for a least-squares linear regression line that is used to predict y values ​​from x values. If you call the two data arrays X's and Y's, earlier versions of Excel used a single pass through the data to compute the sum of squares of X's, the sum of squares of Y's, the sum of X's, the sum of Y's, the sum of XY's, and the count of the number of observations in each array. These quantities were then combined into the computational formula that is provided in the Help file in earlier versions of Excel. Replacing a one-tailed approach by a two-tailed approach guarantees better numeric performance of STEYX in Excel 2003 and in later versions of Excel. The results in Excel 2003 and in later versions of Excel will never be less accurate than the results in earlier versions.

Advanced Excel Small Formula

Small Formula in Excel

The SMALL function is useful when you want to 

extract the kth smallest value from a dataset.

Description of Small Formula:

The Excel SMALL function returns numeric values ​​based 

on their position in a list, ranked by value. The Microsoft 

Excel SMALL function returns the nth smallest value from

 a set of values. The SMALL function is a built-in function

 in Excel that is classified as a statistical function. It can

 be used as a worksheet function in Excel. As a worksheet 

function, the SMALL function can be entered as part of a 

formula in a cell of a worksheet. Returns the kth smallest

 value in a dataset. Use this function to return values ​​at

 a specific relative position in the dataset. 

Syntax of Small Formula

=SMALL(ARRAY, K)

Examples of Small Formula

the first, second or third fastest time in a race.

Jockey No	Time taken	Result of race	Time taken
1	5:45	1	4:05
2	6:01	2	4:10
3	4:10	3	4:19
4	5:13
5	4:19
6	6:22
7	4:05
8	6:50
9	7:54
10	6:57

Errors in Small formula

If array is empty, SMALL returns the #NUM! error value.

If k ≤ 0 or if k exceeds the number of data points, 

SMALL returns the #NUM! error value.

If n is the number of data points in array, 

SMALL(array,1) equals the smallest value, 

and SMALL(array,n) equals the largest value.
