    Which Steps should you take when you notice special causes in a control chart?

    • Do nothing

    • Continue taking data measurements to confirm your belief

    • Stop and identify the Special Causes

    • Stop, identify the special Causes and eliminate them

    Correct Answer
    A. Stop, identify the special Causes and eliminate them
    Explanation
    When special causes are noticed in a control chart, it is important to stop and identify them. This is because special causes indicate that there are factors in the process that are causing variation beyond the normal random variation. By identifying these special causes, it becomes possible to understand and eliminate them, thereby improving the overall process and reducing variation. Simply continuing to take data measurements may confirm the presence of special causes, but it does not address the root cause of the problem. Doing nothing is also not recommended as it allows the special causes to persist and potentially worsen the process performance.

    A normal distribution is characterized by being bell-shaped, meaning that the majority of the data falls around the mean and tapers off towards the tails. It is also symmetrical about the mean, meaning that the data is equally distributed on both sides of the mean. Additionally, a normal distribution has a single mode, indicating that there is one value that occurs most frequently in the data. Therefore, the given answer accurately describes the characteristics of a normal distribution.

    A company generates 12,000 orders per month.  Each order has the possibility of 4 errors.  Approximately how many opportunities for defects are provided during the year?

    • 1,000,000

    • 84,000

    • 144,000

    • 576,000

    Correct Answer
    A. 576,000
    Explanation
    The company generates 12,000 orders per month, and each order has the possibility of 4 errors. To calculate the total number of opportunities for defects provided during the year, we need to multiply the number of orders per month by the number of errors per order and then multiply that by 12 (the number of months in a year). Thus, 12,000 orders per month * 4 errors per order * 12 months = 576,000 opportunities for defects during the year.

    Provides relationship between two variables, and provides a visual correlation coefficient

    • Scatter Diagram

    • Cause and Effect Chart

    • Box Plot

    • Trend Line

    Correct Answer
    A. Scatter Diagram
    Explanation
    A scatter diagram is a graphical tool that displays the relationship between two variables. It plots data points on a graph, with one variable represented on the x-axis and the other on the y-axis. By visually examining the pattern of the points, we can determine if there is a correlation between the variables. The scatter diagram also provides a visual correlation coefficient, which indicates the strength and direction of the relationship between the variables. Therefore, a scatter diagram is the correct answer as it provides both the relationship between variables and a visual correlation coefficient.
