                   Ans.   A variable is a characteristic that is measured and can have multiple values.
                    18.   What do you mean by level of measurement?
                   Ans.   The level of measurement refers to the relationship between the values given to the attributes of a variable.

                    19.   What is data matrix?
                   Ans.   The tabular format to present cases and variables used in statistical study is known as a data matrix.
                    20.   What is the frequency of a particular data value?
                   Ans.   The frequency of a particular data value is the number of occurrences of that data value in a dataset.
                    21.   When is the distribution is symmetric?

                   Ans.   Distribution is symmetric if its left half forms a mirror image of its right half.
                    22.   How to identify a distribution which is not symmetric?
                   Ans.     A distribution that is not symmetric has values that tend to be more spread out on one side of the graph than
                          on the other. A distribution that is not symmetric can be left-skewed or right-skewed.
                    23.   In which type of distribution the median, mean, and mode are the same?

                   Ans.   In Symmetric distribution, the median, mean, and mode are the same.
                    24.   What is mean?
                   Ans.   The mean is the average or the most common value in a group of numbers.
                    25.   What do you mean by median?
                   Ans.   The median is the middle value in a given list of numbers arranged in ascending or descending order.

                    26.   Define mode.
                   Ans.   The mode is the value that appears most often in a given list of numbers.

                   Ans.   Rescue robots perform dangerous search and rescue missions using machine intelligence systems.
                    30.   What is ConvNetQuake?

                   Ans.   Thibaut Perol is a deep learning scientist who leads an AI project called ConvNetQuake.
                    31.   Why is AI Ethics Important?
                   Ans.     AI Ethics framework is important because it highlights the risks and benefits of artificial intelligence tools, and
                          provides guidelines for their responsible use.
