查找包含特定值的单元格范围

Question

我正在尝试在类似于此的表格上使用百分位数方法：

+--------+-------------+-------+
| Grade  | StudentName | Score |
+--------+-------------+-------+
| Grade1 | StudentA    | 55    |
| Grade1 | StudentB    | 65    |
| Grade1 | StudentC    | 46    |
| Grade2 | StudentA    | 77    |
| Grade2 | StudentB    | 55    |
| Grade2 | StudentC    | 62    |
| ...    | ...         | ...   |
+--------+-------------+-------+

我正在尝试计算以下矩阵中每个等级的四分位数。

+---------+-----------------+-----------------+-----+ 
|         | 25th Percentile | 50th Percentile | ... |
+---------+-----------------+-----------------+-----+
| Grade 1 |                 |                 |     |
| Grade 2 |                 |                 |     |
| Grade 3 |                 |                 |     |
| ...     |                 |                 |     |
+---------+-----------------+-----------------+-----+

问题在于百分位公式需要一系列细胞。如何动态查找包含Grade1的单元格/范围？

Answer 1

F2的公式：

=QUARTILE(IF($A$2:$A$7=$E2,$C$2:$C$7,""),F$1)

然后按CTRL + SHIFT + ENTER使其成为带有大括号的数组公式。
