<h1>F.TEST Function</h1>
|
|
<p>The <b>F.TEST</b> function is one of the <a href="../UsageInstructions/InsertFunction.htm#statistical" onclick="onhyperlinkclick(this)">statistical functions</a>. 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>
|
|
<h3>Syntax</h3>
|
|
<p><b><em>F.TEST(array1, array2)</em></b></p>
|
|
<p>The <b>F.TEST</b> function has the following arguments:</p>
|
|
<table style="width: 40%">
|
|
<tr>
|
|
<th style="background-color: #f4f4f4" width="150ch"><b>Argument</b></th>
|
|
<th style="background-color: #f4f4f4"><b>Description</b></th>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>array1</em></b></td>
|
|
<td>The first range of values.</td>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>array2</em></b></td>

|
|
</tr>
|
|
</table>
|
|
<h3>Notes</h3>
|
|
<p>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>
