The correct answer is (b), median.
An ogive is a graphical representation of the cumulative frequency distribution of a variable. It is a line graph that shows the cumulative proportion of observations that are less than or equal to a certain value.
The median is the middle value in a set of data. It is the value that divides the set into two equal parts, with half of the values being less than or equal to the median and half of the values being greater than or equal to the median.
The ogive for the more than type intersects the ogive for the less than type at the median. This is because the median is the value that divides the set into two equal parts, and the ogives show the cumulative proportion of observations that are less than or equal to a certain value.
The mean is the average of a set of data. It is calculated by adding up all of the values in the set and dividing by the number of values in the set.
The mode is the most frequent value in a set of data. It is the value that occurs the most often in the set.
The origin is the point at which the x-axis and the y-axis intersect. It is the point with coordinates (0, 0).
The ogive for the more than type and the ogive for the less than type do not intersect at the mean, the mode, or the origin.
