Students name:. Institution affiliation:. Date:. Asthma. Asthma is a disease that affects the respiratory system. It causes Bronchial mucosa inflammation resulting to airflow obstruction, airway constriction and bronchial hyperresponsiveness.. : A British biometrician, Sir Francis Galton, defined regression as ‘stepping back towards the average’. He found that the offspring of abnormally tall or short parents tends to regress or step back to average.. Fun facts about the regression line. Equation of regression line: . If we convert our X and Y scores to . z. x. and . z. y. , the regression line through the z-scores is:. Because the means of the z-scores are zero and the standard deviations are 1.. Step 1 – Data Collection: Parts are collected from the production line and product measurements are completed. After completing the entire process, they are subjected to a quality test. These product measurements and quality test results are combined into a dataset and used for building the model. This dataset is examined thoroughly to ensure it is as clean as possible..
