## What is the difference between the highest and the lowest scores of items?

The difference refers to the mathematical operation of subtraction, or removing a certain amount from a number. In this question, they are referring to the difference between the highest and lowest scores, which means highest score – lowest score = difference.

## What is the difference between the highest and lowest values of the observations called?

Range is the difference between the highest and lowest data value in the set.

**Can there be 2 modes?**

A set of numbers can have more than one mode (this is known as bimodal if there are two modes) if there are multiple numbers that occur with equal frequency, and more times than the others in the set.

**What is the most common measure of central tendency?**

The mean

The mean is the most frequently used measure of central tendency because it uses all values in the data set to give you an average.

### What is the highest and lowest observation?

What is the range of data? Range is the difference between the highest and the lowest observation. The highest marks are 9 and the lowest marks are 1.

### What observation occurs most often?

mode

We know that the observation which occur most frequently is known as mode.

**What if there are 2 modes?**

If there are two numbers that appear most often (and the same number of times) then the data has two modes. This is called bimodal. If there are more than 2 then the data would be called multimodal. If all the numbers appear the same number of times, then the data set has no modes.

**What is the mode if there are no repeating numbers?**

The “mode” is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list.

## Which measure of central tendency is not affected by extreme scores?

Median

Median. The median is the middle value in a distribution. It is the point at which half of the scores are above, and half of the scores are below. It is not affected by outliers, so the median is preferred as a measure of central tendency when a distribution has extreme scores.

## What is the most common measure?

Measures of central tendency help you find the middle, or the average, of a data set. The 3 most common measures of central tendency are the mean, median and mode. The mode is the most frequent value. The median is the middle number in an ordered data set.

**Which set of data has a mean of 15 a range of 22 a median of 14 and a mode of 14?**

The Mode is the number that occurs most number of times. In the given data, 14 occurs two times. so, 14 is the mode. so, range is 22.

**Is the set of observation that occur most often?**

Mode

In a set of observations, the observation that occurs the most often is called Mode.
