<h1>F.TEST Function</h1>
|
|||
|
|
<p>The <b>F.TEST</b> function is one of the statistical functions. It is used to return the result of an F-test, the two-tailed probability that the variances in <b><em>array1</em></b> and <b><em>array2</em></b> are not significantly different. Use this function to determine whether two samples have different variances.</p>
|
|||
|
|
<p>The <b>F.TEST</b> function syntax is:</p>
|
|||
|
|
<p style="text-indent: 150px;"><b><em>F.TEST(array1, array2)</em></b></p>
|
|||
|
|
<p><em>where</em></p>
|
|||
|
|
<p style="text-indent: 50px;"><b><em>array1</em></b> is the first range of values.</p>
|
|||
|
|
<p style="text-indent: 50px;"><b><em>array2</em></b> is the second range of values.</p>
|
|||
|
|
<p>The values can be entered manually or included into the cells you make reference to. Text, logical values and empty cells are ignored, cells that contain zero values are included. If the number of values in a data range is less than 2 or a variance of an array is 0, the function returns the #DIV/0! error value.</p>
|
|||
|
|
<p>To apply the <b>F.TEST</b> function,</p>
|
|||
|
|
<ol>
|
|||
|
|
<li>select the cell where you wish to display the result,</li>
|
|||
|
|
<li>click the <b>Insert function</b> <img alt="Insert function icon" src="../images/insertfunction.png" /> icon situated at the top toolbar,
|
|||
|
|
<br />or right-click within a selected cell and select the <b>Insert Function</b> option from the menu,
|
|||
|
|
<br />or click the <img alt="Function icon" src="../images/function.png" /> icon situated at the formula bar,
|
|||
|
|
</li>
|
|||
|
|
<li>select the <b>Statistical</b> function group from the list,</li>
|
|||
|
|
<li>click the <b>F.TEST</b> function,</li>
|
|||
|
|
<li>enter the required arguments separating them by commas,</li>
|
|||
|
|
<li>press the <b>Enter</b> button.</li>
|
|||
|
|
</ol>
|
|||
|
|
<p>The result will be displayed in the selected cell.</p>
