Look at the relationship graphs of lines and graphs of the absolute value of lines
The absolute value function in WolframAlpha is “abs”. Putting this in front of (x+4) means the absolute value of the quantity x + 4. Press return to give the following result. The graph consists of a horizontal section at y = -1 and another at y = 1. These sections are connected by a vertical line at x = -4.
Students will review the definition of absolute value, interpreting it as distance, and solving basic absolute value equations with number lines.
Mean: Use the mean() command to obtain the arithmetic mean of a list of numbers, which can be defined explicitly (e.g., $\mathrm{mean}([2.5,5.7,15,3]) $), or referred to via a variable name (e.g., $\mathrm{mean}(a_1) $).
7 cze 2024 · Perform a one-sample t-test of whether the mean of the population from which list is sampled differs from value (the null hypothesis). The output includes p -values for both the one-tailed versions (labeled "less than" and "greater than") and the two-tailed version (labeled "not equal") of the test.
13 sty 2019 · How would I graph an equation with an absolute value inside an absolute value? For example, $\left|-\left|x\right|+1\right|+\left|y-2\right|=3$ I tried graphing this on Desmos and it gave me some weird closed polygon.
This activity provides an exploration of the meaning and process of mean absolute deviation. At the end of the lesson there is a slide that can be used for any data set (with `\le12` data points) to walk students through the process step-by-step, giving feedback for any errors along the way.
