CLASS LIMITS: The originally assigned extreme values of classes are called class limits, viz. FREQUENCY DISTRIBUTION: The organization of raw data in table form with classes and frequencies. CUMULATIVE FREQUENCY: The running total of the frequencies at each class interval level. FREQUENCY: The number of times a certain value or class of values occurs. SAMPLE: The collection of data from subgroup or subset of the population. CENSUS: The collection of data from every element in a population or universe or arena of statistical enquiry. (iv) Mixed Curve (Second Most Common Shape) GLOSSARY: (iii) J – Shaped: Simple J – shaped & Inverted J – Shaped This is broadly divided into four shapes: ILLUSTRATIONS OF PRESENTATION OF DATA:īar Diagrams: source-internet source-internetĪ smooth join of all vertices of a frequency polygon.
#Brief discussion about tabulo series#
Multiple axis bar diagram or Multiple axis Line diagram is used when units in the two series are differentįrequency, when continuously added from lower to higher, is called "less than cumulative frequency" and when continuously added from higher to lower, is called "more than cumulative frequency".Ī particular frequency, divided by total is called relative frequency.įrequency divided by class size is called Frequency Density. Multiple bar diagram or Multiple Line diagram is used when two related series (in same unit) are to be compared Bar Diagram and Line Diagram can both be of simple and multiple types
Bar Diagram and Line Diagram are inter-convertible (c) Ogives: (i) Less than type Ogives (ii) More than type Ogives Notes: Three most common frequency diagrams are: Mostly class-intervals are presented via this mode.
Frequency Diagrams: Frequency Data are presented. Non-Frequency Diagrams: Non-frequency diagrams correspond to the data which are NOT frequency data.ī. Kailasha Foundation – Fun & Learn Portal LMS Directory *Footnotes: The entire upper part of the table is called BOX HEAD.Ī.
