FAQs on Introduction to Statistics
| 1. What is statistics? |  |
Ans. Statistics is a branch of mathematics that deals with collecting, analysing, interpreting, presenting, and organising data. It helps in making informed decisions based on data analysis and is widely used in various fields such as economics, psychology, and social sciences.
| 2. What are the types of data in statistics? | |
Ans. In statistics, data can be classified into two main types: qualitative and quantitative. Qualitative data refers to non-numeric information that describes characteristics or qualities, such as colours or names. Quantitative data is numeric and can be measured, further divided into discrete (whole numbers) and continuous (any value within a range) data.
| 3. What is the importance of measures of central tendency? | |
Ans. Measures of central tendency, which include mean, median, and mode, are important because they summarise a set of data by identifying the central point around which the data clusters. This helps in understanding the general trend of the data and makes it easier to compare different datasets.
| 4. How is the mean calculated? | |
Ans. The mean, also known as the average, is calculated by adding all the values in a dataset and then dividing by the total number of values. For example, for the values 2, 4, and 6, the mean would be (2 + 4 + 6) / 3 = 4.
| 5. What is a frequency distribution? | |
Ans. A frequency distribution is a statistical tool that shows how often each value or range of values occurs in a dataset. It is typically presented in a table format, where the data is grouped into intervals, and the frequency (number of occurrences) of each interval is listed, helping to visualise the distribution of the data.
