Viney Corporation Senior Executive Officer Interview Questions, Process, and Tips

Skewness is a measure of the asymmetry of a probability distribution. The symmetric value in skewness is zero.

• Skewness measures the degree of asymmetry in a distribution.

• A positive skewness indicates a longer tail on the right side of the distribution.

• A negative skewness indicates a longer tail on the left side of the distribution.

• A symmetric distribution has a skewness of zero.

Kurtosis is a measure of the shape of a probability distribution. Leptokurtic distributions have a higher peak and heavier tails.

• Kurtosis measures the degree of peakedness or flatness of a distribution compared to a normal distribution.

• Leptokurtic distributions have a kurtosis greater than 3, indicating a higher peak and heavier tails than a normal distribution.

• Examples of leptokurtic distributions include the t-distri

PPAP requires several documents. Here are some examples:

Cp, cpk measure process capability while Pp, ppk measure process performance.

• Cp and cpk are used for measuring how well a process is performing within its specification limits.

• Pp and ppk are used for measuring how well a process is performing between its specification limits.

• Cp and Pp are based on the standard deviation of the process, while cpk and ppk are based on the deviation of the process from the target value.

• Cp...read more

Sigma is a statistical measure of process variation in SPC. CP and CPK are used to calculate sigma value.

• Sigma is a measure of how much a process deviates from its target value.

• It is calculated using the standard deviation of the process data.

• CP and CPK are used to calculate sigma value in SPC.

• CP measures the capability of a process to meet the customer's specifications.

• CPK measures the capability of a process to meet ...read more

CP and Cpk are statistical process control measures used to assess process capability.

• CP measures the potential capability of a process to meet the specifications, while Cpk measures the actual capability of a process to meet the specifications.

• CP is calculated using the formula (USL-LSL)/(6*sigma), while Cpk is calculated using the formula min[(USL-mean)/(3*sigma), (mean-LSL)/(3*sigma)].

• CP only considers the spread of...read more

CP and CPK are statistical measures of process capability. Acceptable values depend on the industry and specific process.

• Acceptable values vary by industry and process

• Generally, a CP of 1.33 and a CPK of 1.67 are considered acceptable

• Higher values indicate better process capability

• Values below 1 indicate a process that needs improvement

• CPK takes into account the process mean and standard deviation, while CP only consid
