Because the CCSS is currently in its first year of implementation at WWHS, my current students have not been formally introduced to the primary topics in this progression. List the transformations whether given the graph or equation of the absolute value function.

Karl Pearson Purpose To roughly assess the probability distribution of a given variable by depicting the frequencies of observations occurring in certain ranges of values. A histogram is an accurate representation of the distribution of numerical data.

It is an estimate of the probability distribution of a continuous variable quantitative variable and was first introduced by Karl Pearson. To construct a histogram, the first step is to " bin " or " bucket " the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval.

The bins are usually specified as consecutive, non-overlapping intervals of a variable. The bins intervals must be adjacent, and are often but are not required to be of equal size. A histogram may also be normalized to display "relative" frequencies. It then shows the proportion of cases that fall into each of several categorieswith the sum of the heights equaling 1.

However, bins need not be of equal width; in that case, the erected rectangle is defined to have its area proportional to the frequency of cases in the bin. Examples of variable bin width are displayed on Census bureau data below. As the adjacent bins leave no gaps, the rectangles of a histogram touch each other to indicate that the original variable is continuous.

The total area of a histogram used for probability density is always normalized to 1.

If the length of the intervals on the x-axis are all 1, then a histogram is identical to a relative frequency plot. A histogram can be thought of as a simplistic kernel density estimationwhich uses a kernel to smooth frequencies over the bins.

This yields a smoother probability density function, which will in general more accurately reflect distribution of the underlying variable. The density estimate could be plotted as an alternative to the histogram, and is usually drawn as a curve rather than a set of boxes.

Histograms are nevertheless preferred in applications, when their statistical properties need to be modeled. The correlated variation of a kernel density estimate is very difficult to describe mathematically, while it is simple for a histogram where each bin varies independently.

An alternative to kernel density estimation is the average shifted histogram, [5] which is fast to compute and gives a smooth curve estimate of the density without using kernels.

The histogram is one of the seven basic tools of quality control. A histogram is used for continuous datawhere the bins represent ranges of data, while a bar chart is a plot of categorical variables.

Some authors recommend that bar charts have gaps between the rectangles to clarify the distinction.Math Worksheets Absolute Value Equations Myscres. Absolute Value Word Problem You. Kateho Solving Absolute Value Equations And Inequalities.

This tutorial takes you through that process step-by-step! Take an absolute value equation and perform a vertical and horizontal translation to create a new equation.

Watch it all in this tutorial. Absolute Value Equations Worksheet 1 - Here is a 16 problem multiple choice worksheet where you will determine the solutions to equations containing absolute value.

You should check each solution by plugging them into the given equation. But if \(x\) is a positive number, then the absolute value of \(x\) is itself.

Unless \(x = 0\), every absolute value equation should have two solutions. Let’s see if we can solve absolute value equations now.

Practice your understanding of graphing absolute value inequalities with the help of our quiz. Others will ask you to match the equation with the graph. Quiz & Worksheet Goals.
