Number of Defective Units given Reliability Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Defective Units = (100-Reliability Number)*Tested Units/100
D = (100-RN)*T_u/100
This formula uses 3 Variables

Variables Used

Defective Units - The Defective Units here refer to the number of defective objects or units that are considered for sampling.
Reliability Number - The Reliability Number is the overall consistency of measurement. It increases as the sample size is increased.
Tested Units - The Tested Units refer to the number of units or objects tested for conducting the sampling.

STEP 1: Convert Input(s) to Base Unit

Reliability Number: 2.01 --> No Conversion Required
Tested Units: 100 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = (100-RN)*T_u/100 --> (100-2.01)*100/100

Evaluating ... ...

D = 97.99

STEP 3: Convert Result to Output's Unit

97.99 --> No Conversion Required

FINAL ANSWER

97.99 <-- Defective Units

(Calculation completed in 00.004 seconds)

< 8 Quality Control in Construction Calculators

Proportion Non-Confirming in Sample

Go Non-Conforming Proportion = Number of Non-Conforming/Number of Items in Sample

Number Non-Confirming in Sample

Go Number of Non-Conforming = Number of Rejected/Number of Sample

Coefficient of Variation

Go Variation Coefficient = Standard Deviation*100/Arithmetic Mean

Number of Units Tested given Reliability Number

Go Tested Units = (100*Defective Units)/(100-Reliability Number)

Reliability Number

Go Reliability Number = 100-((Defective Units/Tested Units)*100)

Number of Defective Units given Reliability Number

Go Defective Units = (100-Reliability Number)*Tested Units/100

Average Proportion Non-Confirming

Go Average Proportion = Number of Rejected/Number of Inspected

Average Non-Conformities in Inspected Unit

Go Average Non-Conformity = Number of Rejected/Unit Numbers

Number of Defective Units given Reliability Number Formula

Defective Units = (100-Reliability Number)*Tested Units/100
D = (100-RN)*T_u/100

What is Sampling?

In statistics, quality assurance, and survey methodology, sampling is the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population. The methodology used to sample from a larger population depends on the type of analysis being performed, but it may include simple random sampling or systematic sampling.

What are the major Quality Control Methods Adopted?

The major quality control methods adopted are as follows
1. Inspection: Firstly, it is carried out for the materials of construction for checking their quality and acceptability. later, during the process or during construction.
2. Testing: It is the examination conducted for the material or the product for finding its performance.
3. Sampling: Sampling is a process used in statistical analysis in which a predetermined number of observations are taken from a larger population.
