The outlier formula
WebbTo detect extreme outliers do the same, but multiply by 3 instead: extreme.threshold.upper = (iqr * 3) + upperq extreme.threshold.lower = lowerq - (iqr * 3) Any data point outside (> extreme.threshold.upper or < extreme.threshold.lower) these values is an extreme outlier. Hope this helps. Webb12 apr. 2024 · When 1 of the 5 determinants of demand changes, we show the change as a shift of the entire demand curve . When demand increases, the demand curve shifts to the right. A rightward shift demonstrates that consumers are now willing to purchase a higher quantity at every price. When demand decreases, the demand curve shifts to the left.
