The pricing of household work can be based on standardized times established for component parts of the job. Techniques for determining these standardized times and the component parts were developed in a study conducted at Purdue University and supported by a federal grant. After a preliminary survey of homemaker practices in cleaning living areas of 20 homes, a laboratory study was made which used eight household workers to perform dusting operations under controlled conditions. A work estimation formula was derived from these task situations. A multiple regression model was developed from the dusting and vacuuming of 20 family-living areas of 12 nonrandomly selected households by graduate research and laboratory assistants. Quota sampling was used to select 32 homes in which a regression equation was used to establish the factors most useful in predicting time use from a replication of the previous tasks by seven household workers. The following independent variables were important in estimating or predicting variation in cleaning time: (1) square foot area of the room, (2) moved-item density of the room, (3) total furniture density, (4) accessory rating, (5) type of heating, (6) percentage of carpet in the room, (7) dexterity time score of the worker, and (8) other variables relating to the furniture and the homemaker.
