This is identical to question 394724. An ogive is the curve obtained by plotting cumulative frequencies against class boundaries. The statement 'A curve obtained by plotting cumulative frequencies is called an Ogive' is the standard definition in statistics.

Histograms use rectangular bars to show frequency, while frequency polygons use line segments connecting points. They are fundamentally different in visual representation.

Ogives can be constructed for both 'less than' cumulative frequency distributions and 'more than' cumulative frequency distributions.

Ogives are useful tools in statistics to estimate positional measures such as the median, quartiles, and other percentiles.

The point where the 'less than' ogive and 'more than' ogive intersect on the horizontal axis corresponds to the median of the data distribution.

Plotting cumulative frequencies results in an S-shaped curve known as an Ogive.

Pictograms represent data using pictures or symbols, which are non-dimensional compared to geometric diagrams like squares or cubes.

The choice of a chart is influenced by the purpose of the analysis, the type of data (qualitative/quantitative), and the nature of the data distribution.

A bar chart is considered a one-dimensional diagram because only the height (or length) of the bar varies to represent the magnitude of the data.

An Ogive curve requires cumulative frequencies because it plots the total frequency up to a certain point against the class boundaries.
