The current staging system is recommended for the classification of both non–small cell and small cell lung carcinomas and for carcinoid tumors of the lung . TNM Staging of Lung Cancer Primary Tumor (T) The “T” staging of bronchogenic carcinoma is a bit complex compared to others. Five things must be checked before assigning a T classification. They can be remembered with a mnemonic: ABCDE. 1. Atelectasis 2. Bronchus involvement (bronchoscopy) 3. Contiguous conquer (Adjacent site invasion) 4. Diameter in cm 5. Elevated nodules

  What’s the difference between statistical and practical significance? While  statistical significance   shows that an effect exists in a study,  practical significance  shows that the effect is large enough to be meaningful in the real world. Statistical significance is denoted by  p -values  whereas practical significance is represented by  effect sizes . https://www.researchgate.net/publication/323661269/figure/tbl1/AS:669150552784905@1536549332972/Interpretation-of-Coefficient-Correlation-Scale_W640.jpg

Often in statistics we’re interested in measuring  population parameters  – numbers that describe some characteristic of an entire population.  Two of the most common population parameters are: 1. Population mean:  the mean value of some variable in a population (e.g. the mean height of males in the U.S.) 2. Population proportion:  the proportion of some variable in a population (e.g. the proportion of residents in a county who support a certain law) Although we’re interested in measuring these parameters, it’s usually too costly and time-consuming to actually go around and collect data on every individual in a population in order to calculate the population parameter. Instead, we typically take a ra
