5. The SMALL function

a) Meaning

The SMALL () function is a calculation function in excel that produces the smallest k-value of a data set

b) Syntax

= SMALL (array, k)

Inside:

+ Array is an array or range of numeric data that you want to determine its kth smallest value.

+ K is the position (from the smallest value) in the array or range of data to return.

*Attention:

- The arguments of the calculation function are required values

- In case the array is empty then the SMALL function will give the #NUM! Error result..

- In case k is less than or equal to 0 or if k exceeds the number of data points, then the SMALL function will produce the #NUM! Error result .

c) Example

In part 6

6. LARGE function

a) Meaning

The LARGE () function is a calculation function in excel that produces the k-largest value of a data set

b) Syntax

= LARGE (array, k)

Inside:

+ array: An array or range of data containing the kth largest value in it.

+ k: What is the largest position (the largest adjective is No. 1) in the array you want to return.

* Attention

- If the argument in the array is a blank -> the function returns the #NUM! Error value .

- If k ≤ 0 or k is greater than the number of data points in the array -> the function returns the #NUM! Error value

- If n is the number of data points of the array, then:

+ LARGE (array, 1) -> returns the largest value in the array array.

+ LARGE (array, n) -> returns the smallest value in the array array.

c) Example

In the data table 'REVENUE REPORT' the following stores.Find stores with the largest and smallest sales

+ The largest revenue = LARGE (B4: B10,1)

+ Minimum revenue = SMALL (B4: B10,1)

= MIN (number1, number2 .)

+ number1, number2 . are input parameters that can be numbers, names, ranges of cells or reference values.Maximum 256 input parameters.

* Attention

-If the argument list contains no numbers, the Min function returns a value of 0.

-If the argument is an array or reference, only numbers in that array or reference are used.And empty cells, logical values, or text are ignored.

-The argument is text or the error value does not convert into numbers then the error function.

-The logical values ​​and numbers of text you enter directly into the argument list will be calculated.

c) Example

Give the following data table.Find ventricular click

= MIN (C5: C14) => is 4.9
