Answer:
Concept:
• Tally marks determine class frequency.
• Economic problem arises due to All of the above.
• Statistics in singular sense includes Presentation of data.
• Frequency of a variable is always An integer.
Explanation:
• Tally marks determine the frequency of classes.
class boundaries are the values that separate the classes.
We use the following steps to calculate class boundaries in a frequency distribution:
1. Subtract the upper limit for the first class from the lower limit for the second class.
2. Divide the result by two.
3. Subtract the result from the lower class limit and add the result to the upper limit for each class.
• Economic problem arises because of All of the above.
An economic problem arises due to the fact that resources are scarce, resources have alternative uses, and human needs are unlimited.
• Statistics in a unified sense includes the presentation of data.
The word statistics is associated with the concept of state.
In the plural sense, numerical data or statements of fact relating to any area of human experience are called statistics.
On the other hand, the term statistics in a unified sense means a collection of scientific methods that deal with the collection, presentation, analysis and interpretation of numerical data. This unique sense of statistics is used and contributed to in various branches of statistics.
Systematic organization is essential for organizing data after data collection. They are organized and presented in tables based on rows and columns. This process is known as data presentation.
• The frequency of a variable is always an integer number.
Frequency is the number of occurrences of a value, so it will always be an integer.
