Statistics Quizz 1

If distribution is symmetrical, then:

• AM≤Median≥Mode

• AM≤Median≤Mode

• AM≥Median≤Mode

• AM=Median=Mode

The AM should be used when the distribution:

• Not skewed

• Does not have very large and small items

• Does not have an open end class

• All of the above

The following is the appropriate average for the construction of index numbers

• AM

• HM

• Median

• GM

Bar diagram is suitable for ______ frequency distribution.

• Circular

• Continuous

• Discrete

• None of the above

The ratio of standard deviation and mean is known as:

• Variance

• Coefficient of variability

• Mean deviation

• Standard error

One dimensional diagram of data representation is:

• Bar diagram

• Square

• Circle

• Cube

Two dimensional representation of data is:

• Histogram

• Bar diagram

Cumulative frequency curve is also known as:

• Ogive curve

• Frequency polygon

• Smooth curve

• Pie chart

The difference between the highest and lowest value is a sample refers to:

• Range

• Mean

• Standard deviation

• Standard error

The characteristics of ideal measure of central tendency includes:

• Based on all observations

• Least affected by sampling fluctuation

• Subjected to further algebric operations

• All of the above
