## What is the best measure of central tendency for a bimodal distribution?

the mode

For bimodal distributions, the only measure that can capture central tendency accurately is the mode. The mode is the most frequently occurring number within a data set.

**Does a box plot show central tendency?**

The central tendency is defined as the typical value of a set of data. A box plot is used to compare multiple groups of data, and it shows the median, interquartile range, and maximum and minimum values of the data. Remember that the interquartile range is the middle 50% of the data.

**Can a box plot be bimodal?**

A: Box plot for a sample from a random variable that follows a mixture of two normal distributions. The bimodality is not visible in this graph.

### What does a bimodal distribution tell you?

What does a Bimodal Distribution tell you? You’ve got two peaks of data, which usually indicates you’ve got two different groups. For example, exam scores tend to be normally distributed with a single peak.

**Which measure of central tendency is the most powerful?**

The median is the most informative measure of central tendency for skewed distributions or distributions with outliers. For example, the median is often used as a measure of central tendency for income distributions, which are generally highly skewed.

**What is the most accurate measure of central tendency?**

Mean

Mean is generally considered the best measure of central tendency and the most frequently used one. However, there are some situations where the other measures of central tendency are preferred. There are few extreme scores in the distribution.

## How do histograms show central tendency?

A histogram of your data shows the frequency of responses for each possible number of books. From looking at the chart, you see that there is a normal distribution. The mean, median and mode are all equal; the central tendency of this data set is 8.

**How do you interpret box plots?**

The median (middle quartile) marks the mid-point of the data and is shown by the line that divides the box into two parts. Half the scores are greater than or equal to this value and half are less. The middle “box” represents the middle 50% of scores for the group.

**Can you tell if data is bimodal from a boxplot?**

A boxplot can show whether a data set is symmetric (roughly the same on each side when cut down the middle) or skewed (lopsided). A symmetric data set shows the median roughly in the middle of the box. Skewed data show a lopsided boxplot, where the median cuts the box into two unequal pieces.

### Can bimodal distribution be normal?

A bimodal distribution has two peaks (hence the name, bimodal). They are usually a mixture of two unique unimodal (only one peak, for example a normal or Poisson distribution) distributions, relying on two distributed variables X and Y, with a mixture coefficient α.

**How does seasonality play a role in bimodal distribution?**

This clear seasonality suggests that weather factors play a role, either directly or indirectly through intermediate pathways. However, little empirical evidence of the role of these weather factors has been presented.

**How is a bimodal distribution different from a unimodal distribution?**

It patterns bi-modally such that the most frequent tokens of one category occur at one end of a dimension and tokens from another category occur at the other end. This is in contrast to a unimodal distribution in which the most frequent tokens occur between two ends of a continuum.

## How to calculate the central tendency of a distribution?

Understand and calculate four ways the amount of dispersion or variability in a distribution can be determined Understand how skew and level of measurement can help determine which measures of central tendency and variability are most appropriate for a given distribution

**When is multimodal distribution important to show?**

If multimodality is important to show, I’d suggest looking at displays that are better at showing that – the precise choice of display depends on what you most want it to show well.
