The phrase "and a weighted average" is correct and usable in written English.
It can be used when discussing statistical calculations or data analysis that involves averaging values with different levels of importance or weights.
Example: "To determine the overall performance, we calculated the final score using a weighted average of the individual assessments, and a weighted average was essential for accuracy."
Alternatives: "and a weighted mean" or "and a weighted calculation".
The average health weight for each grade of impairment was calculated as the percentage difference in SGRQ score from that found in persons with similar risk factors, and a weighted average health weight for all pulmonary tuberculosis patients was calculated.
When a single summary measure is required, traditional age standardization is used, where an estimate of relative survival is obtained separately in age groups and a weighted average calculated with the weights reflecting an international standard population [ 8].
For each subset we calculated an average value for probability of connection and a weighted average for callosal axonal water fraction, where a weight for a voxel was given as a connection replicability between this voxel and any voxel in a sampled subset.
We report both a non-weighted and a weighted average, in which we apply double weight for clinicians.
Odds ratio of mortality for admission to SU were computed within each strata and a weighted average across strata was derived based on weights proportional to the inverse of the variance of the estimates [15].
A linear regression analysis performed between spatially averaged seasonal NDVI and a weighted average of field measurements explains 59% of the variability for the Gourma region over 1984 2011, and 38% for the Fakara region over 1994 2011.
Costs are presented separately for early and late responders, and as a weighted average for all patients receiving response-guided therapy.
For the unit costing of consultations by a dermatologist we distinguished teaching and non-teaching hospitals and calculated a weighted average unit cost given the fact that 10% of Dutch hospitals are teaching hospitals [ 10].
The fixed effects model assumes that ICU readmission incidence is the same from study to study and provides a weighted average that gives large studies greater weight [ 78].
The securities are backed by mortgages guaranteed by the Federal Housing Administration and Veterans Administration and carry a weighted average coupon of 8percentt and an average maturity of 248 months.
The energy calculation for E. coli O157 H7 can be done by introducing the Derjaguin correction factor73 and by considering the Boltzmann probability factor and obtaining a weighted average across all orientations74.
