When this excessive variation occurs, it is called statistical heterogeneity, or just heterogeneity.

Usually there is only one drawing per species but supplementary ones may be included to show excessive variation.

The cold weather is never too cold and the rainfall is never excessive though its excessive variation is often the cause, symptom and malaise of severe droughts.

However, some of the new sequences contain subsequences that cannot be aligned with any of the previously aligned sequences, due to the excessive variation in these hypervariable regions.

"If you're looking for a subtle difference between two groups," he said, "you want to limit anything that might cause excessive variations from subject to subject."

This additional wedge, with a full swing, falls between the average distances of a sand and pitching wedge, allowing the player to fine-tune their approach shot's distance without needing excessive variations in swing speed.

Lying almost entirely within the tropics, and equally to north and south of the equator, Africa does not show excessive variations of temperature.

He achieved this by using a ratchet-and-pawl mechanism to produce the rotary motion, combined with a flywheel which reduced the otherwise excessive variations in the speed of rotation.

When the process triggers any of the control chart "detection rules", (or alternatively, the process capability is low), other activities may be performed to identify the source of the excessive variation.

When excessive variation is identified by the control-chart detection rules, or the process capability is found lacking, additional effort is exerted to determine causes of that variance.
