What is the definition of decile of ungrouped data?

• The median value of a set of data
• A point that divides the data into 10 equal parts
• The sum of all the data points
• A value that separates the top 10% of the data

In mathematics, where are deciles used?

• Calculations of probability distributions
• Calculating the areas of shapes
• Graphing linear equations
• Finding the angles of a triangle

What is the formula used to calculate decile of ungrouped data?

• Decile = (N+1)*P/10
• Decile = N*P/10
• Decile = N/P*10
• Decile = P/N*10

Which of the following represents the decile of ungrouped data?

• The tenth smallest number in the data set
• The median value of the data set
• The sum of all the data points
• The value that separates the top 10% of the data

What is the range of deciles?

• 0 to 10
• 0 to 100
• 1 to 9
• 1 to 10

What does a higher decile indicate?

• A high percentage of the data set
• A low percentage of the data set
• A higher median of the data set
• A lower median of the data set

Which of the following can be used to calculate decile of ungrouped data?

• Sum of all the data points
• Number of data points
• Percentage of the data set
• All of the above

Which of the following is not a benefit of using deciles?

• It helps to compare data sets of different sizes
• It helps to analyze performance across categories
• It helps to measure the spread of data
• It helps to identify outliers

How many points are used to divide the data using deciles?

• 4 points
• 5 points
• 9 points
• 10 points

What is the order of deciles?

• 1st, 2nd, 3rd ... 9th
• 1st, 3rd, 5th ... 9th
• 1st, 5th, 9th
• 1st, 2nd, 4th ... 10th
