我正在尝试计算excel中三个月的平均销售额,而excel中的customerid。我尝试通过averageIfs函数执行此操作,但没有任何帮助。
A B C
Orderdate sales customerid
5/15/2019 7 1
5/15/2019 48.5 1
4/15/2019 92.94 1
3/17/2019 102.85 1
3/18/2019 49 1
3/18/2019 119.95 1
2/18/2019 58.96 1
1/20/2019 14.6 1
5/16/2019 17 6
4/15/2019 148.5 6
4/12/2019 912.94 6
3/17/2019 102.85 6
9/18/2018 22.34 6
Formula I tried: =AVERAGEIFS(B:B,C:C,C2)
预期输出:
customerid average(3 months)
1 49.48
6 359.48
