Deciles

Deciles is a measure of position that divide a distribution into how may parts?

• 7

• 8

• 9

• 10

What is the formula in finding the position of a given decile?

•  $D_k=\frac{n\ \left(k+1\right)}{10}$  
  

•  $D_n=\frac{k\ \left(n+1\right)}{10}$  

•  $D_k=\frac{k\ \left(n+1\right)}{10}$  

•  $D_n=\frac{n\ \left(k+1\right)}{10}$  

In the formula in finding the position of a given decile, what does n represents?

•  $n^{th}$  decile

• number of data

•  $n^{th}$  percentile

• number of deciles

What decile is the median of the distribution?

• $D_3$

• $D_4$

• $D_5$

• $D_6$

What is the $3^{rd}$  step in solving deciles of ungrouped data?

• Find its position using the given formula

• Interpret the result

• Arrange the data in ascending order

• Identify the value of k and n

What does the $8^{th}$  decile mean?

• 8% of the values fall below  $D_8$  

• 80% of the values fall above  $D_8$  

• 8% of the values fall above  $D_8$  

• 80% of the values fall below  $D_8$  

What method is used when the position of the decile is a decimal?

• Linear Interplotation

• Linear Interpolation
