3 days ago · The Challenge of Finding Control Variables. Identifying and managing control variables can be one of the hardest parts of designing experiments. Researchers must think ahead about potential sources of variation and take steps to reduce their impact. For example, in a study on the effects of a new medicine, control variables might include:
3 days ago · Plot distance on the y -axis for an object moving at constant speed by selecting " y " for the column labeled "Distance (m)." Adjust the scale on the graph so all data points are visible. 2. Choose a model equation (line, parabola, exponential, or inverse) to try and fit the data. 3. Change parameters for that model to fit the data. Questions a.
2 days ago · One of the most important steps as part of data preprocessing is detecting and treating the outliers as they can negatively affect the statistical analysis and the training process of a machine learning algorithm resulting in lower accuracy. In this article, we will be discussing how to handle outliers!

5 days ago · All the examples of hypothesis testing so far have involved counts of outcomes that are dichotomous (categorical data with only two categories—good and bad—or quantitative data that have only two possible values—0 and 1), or have involved quantitative data.
A scatter plot shows the relationship between two continuous variables, x and y. The values for each variable correspond to positions on the x- and y-axis respectively. A dot or some other symbol is placed at the (x, y) coordinates for each pair of variables.
1 day ago · If one wave is A (x) = \sin (2x) A(x) = sin(2x) and the other is B (x) = \sin (2x + \pi) B(x) = sin(2x+π), then they add together to make A + B = 0 A+B = 0 \big ((since \sin (2x + \pi) = - \sin (2x)\big). sin(2x+π) = −sin(2x)). This is known as destructive interference in general, when adding two waves results in a wave of smaller amplitude.
