What is the measure of most typical scores in a set of data?
The MODE.
What is a measure of the spread of a set of data?
The standard deviation is the value most used. Others are variance, interquartile range, or range.
What is the mean median mode and range of a number?
These terms apply to a set of data: mode: to the most common number (the number that appears most often) median: the middle number mean: The sum of all the data divided by the number of data items present. range: the difference between the largest and smallest values of data
Which graph shows range and distribution of data set as a whole?
A scatter plot. Most other graphs will summarise some of the data.
What is the meaning of the range equals 9?
It depends on the context. The most likely context is that of a range for a set of data and a range of 9 means that the biggest minus the smallest = 9
What is the term for when most scores in a data set are toward one end of the range of scores?
This is known as a skewed data set.
What is the measure of most typical scores in a set of data?
The MODE.
What do you call it when there are two modal scores in one set?
When there are two modal scores in a set of data, it is called a bimodal distribution. This means that there are two values that occur most frequently in the data set.
How do you find out the modal range?
if data is in the form of frequency distribution then the modal range is the interval containing the highest frequency of observations
What is the value of a data set most likely to be affected by an outlier?
The range.
What does mode and range mean in a math problem?
range is the spread of the data mode is the most common value in the domain
In a study on test scores at different schools which is most clearly a categorical data?
because it shows how much you learned threw out the year

What is the mean median mode and range of a number?
These terms apply to a set of data: mode: to the most common number (the number that appears most often) median: the middle number mean: The sum of all the data divided by the number of data items present. range: the difference between the largest and smallest values of data
In a study on test scores at different schools which of the following is most clearly an example of categorical data?
Name of the school
Which graph shows range and distribution of data set as a whole?
A scatter plot. Most other graphs will summarise some of the data.
Uses of t-score and z-score in the classroom?
Z scores are used for standardized testing done by most school districts. It is the most common way of standardizing data. IQ scores can be standardized using z scores. The mean is 100 and the standard deviation is 15. You use the t score when the sample is small, <30 often. Many behavior ratings use t scores.
