## How do you make an ogive graph?

Ogive Chart

- Draw and mark the horizontal and vertical axes.
- Take the cumulative frequencies along the y-axis (vertical axis) and the upper-class limits on the x-axis (horizontal axis).
- Against each upper-class limit, plot the cumulative frequencies.
- Connect the points with a continuous curve.

## How do you plot graphs in SPSS?

To create the scatterplot, at the top of the data editor, click on graphs > scatter. We will select simple and then click on “define”. We will choose the variable read for the x-axis and the variable write for the y-axis and then click OK. If we double click anywhere on the graph, we will open up the chart editor.

**What does an ogive graph show?**

An ogive graph serves as a graphical representation of the cumulative relative frequency distribution for quantitative variables. In other words, these graphs plot the percentile on the y-axis and the quantitative variable on the x-axis.

### Is ogive a line diagram?

An ogive is a special kind of line graph. This kind of graph looks just like a line graph, but think of an ogive as an “accumulated” line graph. Just like other types of graphs, an ogive does well at representing some kinds of data, and less well at representing others.

### Why are Ogives useful?

Ogives are useful for determining the median, percentiles and five number summary of data. With an ogive we already know how many data values are above or below a certain point, so it is easy to find the middle or a quarter of the data set.

**What are the two types of ogives?**

There are two types of ogives : Less than ogive : Plot the points with the upper limits of the class as abscissae and the corresponding less than cumulative frequencies as ordinates. The points are joined by free hand smooth curve to give less than cumulative frequency curve or the less than Ogive.
