This means the stock price opened higher than it closed the day before, thereby leaving a gap.

Common gaps cannot be placed in a price pattern—they simply represent an area where the price has gapped..

## How do you find the mean of a histogram?

For each histogram bar, we start by multiplying the central x-value to the corresponding bar height. Each of these products corresponds to the sum of all values falling within each bar. Summing all products gives us the total sum of all values, and dividing it by the number of observations yields the mean.

## What does a gap up mean?

## Why do bars touch on a histogram?

## What is a gap in a graph?

Clusters, Gaps, and Outliers A cluster is formed when several data points lie in a small interval. … A gap is an interval that contains no data. An outlier has a value that is much greater than or much less than other data in the set. An outlier may significantly affect the mean of a data set.

## What is the center and spread of a histogram?

If a histogram is bell shaped, it can be parsimoniously described by its center and spread. The center is the location of its axis of symmetry.
