Graph for Time Series Data
Graph of time series is known as-
- Histogram
- Line graph
- Historigram
- Both b & c — Correct Answer
Explanation:
Correct Answer: Both b & c
A Historigram is the specific technical name for the graph of a time series. Because data points are connected over time with straight lines, it is also called a Line graph. Both names are correct for the same representation.
Types of Graphs — Summary
| Graph Type | Used For | Key Feature |
|---|---|---|
| Histogram | Frequency distribution of continuous variable | Adjacent rectangles; no gaps; area = frequency |
| Frequency polygon | Frequency distribution | Points at midpoints of class intervals connected by lines |
| Frequency curve | Frequency distribution | Smooth free-hand curve joining points of frequency polygon |
| Ogive (cumulative frequency curve) | Cumulative frequency distribution | S-shaped curve; used to find median, quartiles |
| Historigram / Line graph (b & c) | Time series data | Data points plotted over time and connected by lines |
Why Histogram is Wrong
- Histogram is for frequency distribution of continuous data — NOT time series
- Histogram has no time axis; Historigram has time on the X-axis
