## What is the mode of a stem-and-leaf plot?

The mode is **the number that occurs the most in a set of data**. You can use a stem-and-leaf plot to find the mean, median and mode of a set of data. To find the mean, add up all of the numbers in the set and divide by the number of values that you added. Then, divide by the number of values, which is 16.

## How do you find the median and mode of a stem-and-leaf plot?

Quote from video: *To find the meeting of a list of numbers first of all make sure the numbers are in size order from smallest to biggest. And then find out which numbers in the middle of those numbers.*

## How do you find the mode?

The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, **put the numbers in order from least to greatest and count how many times each number occurs**. The number that occurs the most is the mode!

## What is the mode of the scores stem leaf?

The mode of the data set is **the score that occurs the most frequently**. Each “stem” in the left column represents the tens digits of the scores; each of the numbers in its row, or “leaf” represents the units digits.

## How do you find the mode if there are two modes?

Quote from the video:

Quote from video: *The most. So even if a number appears twice. If it appears the most it's going to be the mode if more than one number appears twice you're going to have multiple modes.*

## What is this mode?

Quote from the video:

Quote from video: *In this video I'm going to cover how to find the mode of a data set and the mode is the number that occurs the most and that's how I remember it mode.*

## How do you find the mode of a set of data?

**Count how many times each number occurs in the data set**. The mode is the number with the highest tally. It’s ok if there is more than one mode. And if all numbers occur the same number of times there is no mode.

## How do you find the q1 and q3 in a stem and leaf diagram?

Quote from the video:

Quote from video: *So q1 equals 1/2 outside of n plus 1 term now when we're talking about our upper. And lower quartiles our q1 and q3 n.*

## What is mean median and mode?

The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list. This is what is most often meant by an average. **The median is the middle value in a list ordered from smallest to largest.** **The mode is the most frequently occurring value on the list**.

## What are the modes in math?

The mode is **the value that occurs most often**. The mode is the only average that can have no value, one value or more than one value. When finding the mode, it helps to order the numbers first.

## How do you find the lower quartile in a stem-and-leaf plot?

Quote from the video:

Quote from video: *Altogether we have 31 leaves in total. So the word quartile. Sounds like quarter. So to find the lower quartile or q1 the first quarter we have to get a quarter of the total so a quarter of 31.*

## What is the formula for Q1 and Q3?

Quartile Formula:

There are four different formulas to find quartiles: Formula for Lower quartile (Q1) = N + 1 multiplied by (1) divided by (4) Formula for Middle quartile (Q2) = N + 1 multiplied by (2) divided by (4) Formula for Upper quartile (Q3) = N + 1 multiplied by (3) divided by (4)

## How do you find a lower quartile?

To find the lower quartile of a set of data, we can **find the median of the data and then find the median of the first half**. This strategy is similar to dividing a cake into halves, and then dividing one of the halves in half so that you end up with a quarter of the cake.
