Solution
Assuming that you are using SQL and your table name is 'electricity_reading', the query would look like this:
SELECT AVG(h8) AS average_8th_hour_consumption
FROM electricity_reading;
Here's the step by step explanation:
-
SELECT: This keyword is used to select data from a database. -
AVG(h8): This function returns the average value of the 'h8' column. 'h8' is assumed to be the column that records the 8th hour unit consumption. -
AS average_8th_hour_consumption: 'AS' is used to rename a column or table with an alias. Here, we are giving the alias 'average_8th_hour_consumption' to our result. -
FROM electricity_reading: This specifies the table that we are selecting data from, which in this case is 'electricity_reading'.
So, this query will return the average value of the 8th hour unit consumption from the 'electricity_reading' table and display it under the alias 'average_8th_hour_consumption'.
