Organisation of Data - Online Test
Q1. Range is the
Answer : Option A
Explaination / Solution:
The Range is the difference between the lowest and highest values. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
Q2. The frequency distribution of two variables is known as
Answer : Option C
Explaination / Solution:
Bivariate distribution is the combined probability distribution of two randomly different variables. Normally, these can be plotted graphically on x and y axes so their relationship can be analyzed and any relevant causal effect can be identified. This type of data analysis is useful in risk management.
Q3. Cumulative frequency distribution records frequencies on
Answer : Option A
Explaination / Solution:
No Explaination.
Q4. Orderly arrangement of data ultimately takes the shape of a
Answer : Option D
Explaination / Solution:
A frequency distribution is a table that displays the frequency of various outcomes in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample.
Q5. Mid-point is used to calculate the following except
Answer : Option A
Explaination / Solution:
No Explaination.
Q6. How many classes a frequency distribution should have
Answer : Option B
Explaination / Solution:
A frequency distribution is a table that displays the frequency of various outcomes in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample. Too many classes or too few classes might not reveal the basic shape of the data set, also it will be difficult to interpret such frequency distribution.
Q7. Array gives some orders to data by placing the
Answer : Option A
Explaination / Solution:
No Explaination.
Q8. Arrangement of data according to some logical order is termed as
Answer : Option C
Explaination / Solution:
When the data is presented in some specific order and sequence it is called as a statistical series. An ordered sequence of data samples in numerical form used to predict or demonstrate trends through time and space is called statistical series
Q9. The purpose of classification is to
Answer : Option D
Explaination / Solution:
Data classification is the process of organizing data into categories for its most effective and efficient use. A well-planned data classification system makes essential data easy to find and retrieve. This can be of particular importance for risk management, legal discovery, and compliance.
Q10. A good classification should have
Answer : Option A
Explaination / Solution:
A Comprehensive Data Definition refers to a formal data definition that provides a complete, meaningful, easily read, readily understood definition explaining the content and meaning of data.
