Q

What is a Quartile in an Anatomy of a Box Plot?

A

(Q1 and Q3)

*Q1 (First Quartile): The value below which 25% of the data falls.

*Q3 (Third Quartile): The value below which 75% of the data falls.

*These define the edges of the box.

Q

What is the Interquartile Range (IQR) ??

A

*IQR = Q3 - Q1 .

*It measures the spread of the middle 50% of the data.

*Used to detect outliers.

Q

What are Whiskers accoroding to the Anotomy of the Box Plot?

A

*Extend from the box to show the range of the data within 1.5 \times IQR of Q1 and Q3

*Whisker endpoints are the smallest and largest values within this range.

Q

What are Outliers accoring the the Anotomy of a Box Plot?

A

*Data points that fall outside 1.5 \times IQR from Q1 or Q3.

*Represented as individual dots or symbols beyond the whiskers.

Q

What is the Anotomy of the Plot?

A

1.Box:
*The central rectangle shows the interquartile range (Q1 to Q3).
*Represents the middle 50% of the data.

2.Horizontal Line in the Box:
*Indicates the median (Q2).

3.Whiskers:
*Extend to the smallest and largest values within 1.5 \times IQR from the quartiles.

4.Outliers:
*Any values beyond the whiskers are plotted as individual points.

Q

what is skewed disctribution, and what types are there?

A

A skewed distribution occurs when data is not symmetric, with more values concentrated on one side of the mean.

Types: (This left foot = shape is negatively skewed, and right foot shape = positively skewed)
1. Right Skewed (Positively Skewed): Tail is on the right side.
* Most data is on the left.
* Mean > Median.
2. Left Skewed (Negatively Skewed): Tail is on the left side.
* Most data is on the right.
* Mean < Median.
