Find average time between statuses

Hello all,

How would one go about finding the average time between states using the data set I have below? For example, the average time something is in the RUNNING state before it changes to the QUAL state or the average of the UALARM time before it's back to RUNNING.

Hi @Thewill4u ,

If you want to calculate the average duration of each same status like below, here's my solution.

``````let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("fc/RCoMwDAXQX5E8O0zShtq8CZMhuMIEn6T//xsrlhacutdwuDd322BZQ5jCC1pgZO6kI9OQVfHpgg/0ih5ie+1ExVVGO1uHeVjev8pmhYrmX5ipDG8YN9Qr5lIitbK7T2o9IlcQUgk7o7Syz4jLyuk5j3eovnXamBlW5iDGLw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Status = _t, #"Change Date" = _t, Duration = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Status", type text}, {"Change Date", type datetime}, {"Duration", type text}}),
#"Replaced Value" = Table.ReplaceValue(#"Changed Type","-",".",Replacer.ReplaceText,{"Duration"}),
#"Changed Type1" = Table.TransformColumnTypes(#"Replaced Value",{{"Duration", type duration}}),
#"Reversed Rows" = Table.ReverseRows(#"Changed Type1"),
#"Added Index" = Table.AddIndexColumn(#"Reversed Rows", "Index", 0, 1, Int64.Type),
#"Added Custom" = Table.AddColumn(#"Added Index", "Min", each if[Index]=0 then 0 else List.Max(Table.SelectRows(#"Added Index",(x)=> x[Index]<[Index]and x[Status]<>[Status])[Index])+1),
#"Added Custom1" = Table.AddColumn(#"Added Custom", "Max", each if List.Min(Table.SelectRows(#"Added Index",(x)=> x[Index]>[Index]and x[Status]<>[Status])[Index])-1=null then List.Max(#"Added Custom"[Index]) else List.Min(Table.SelectRows(#"Added Index",(x)=> x[Index]>[Index]and x[Status]<>[Status])[Index])-1),
#"Added Custom3" = Table.AddColumn(#"Added Custom1", "Custom", each if[Index]>=[Min]and [Index]<=[Max]then 1 else 0),
#"Grouped Rows" = Table.Group(#"Added Custom3", {"Min", "Max"}, {{"Table", each _, type table [Status=nullable text, Change Date=nullable datetime, Duration=nullable duration, Index=number, Min=number, Max=number, Custom=number]}}),
#"Added Custom4" = Table.AddColumn(#"Grouped Rows", "Average", each List.Average([Table][Duration])),
#"Expanded Count" = Table.ExpandTableColumn(#"Added Custom4", "Table", {"Status", "Change Date", "Duration"}, {"Table.Status", "Table.Change Date", "Table.Duration"}),
#"Removed Columns" = Table.RemoveColumns(#"Expanded Count",{"Max", "Min"}),
#"Reversed Rows1" = Table.ReverseRows(#"Removed Columns")
in
#"Reversed Rows1"``````

I attach my sample below for reference.
