ASSESSMENT-DECILES GROUPED DATA

Front

What are deciles in statistics?

Back

Deciles are statistical measures that divide a set of data into ten equal parts, each representing 10% of the data.

Front

How many equal parts do deciles divide a dataset into?

Back

Deciles divide a dataset into 10 equal parts.

Front

What is the 5th decile (D5) also known as?

Back

The 5th decile (D5) is also known as the median of the dataset.

Front

If a score is in the 8th decile, what does it imply about the score?

Back

It implies that the score is higher than 80% of the scores in the dataset.

Front

What is the relationship between D5 and P50?

Back

D5 is equal to P50, which represents the median of the distribution.

Front

How do you find the 6th decile (D6) in a dataset?

Back

To find D6, arrange the data in ascending order and locate the value that separates the lowest 60% from the highest 40%.

Front

What is the formula to calculate the position of a decile in a dataset?

Back

The position of the k-th decile can be calculated using the formula: P = (k/10) * (N + 1), where N is the number of observations.

Front

What does it mean if a score is above the 7th decile?

Back

It means that the score is higher than 70% of the scores in the dataset.

Front

What is the difference between quartiles and deciles?

Back

Quartiles divide data into 4 equal parts, while deciles divide data into 10 equal parts.

Front

What is the 3rd quartile (Q3) in relation to deciles?

Back

Q3 is equivalent to the 7th decile (D7), representing the value below which 75% of the data falls.
