What frequency distribution graph is appropriate for scores measured on a nominal scale?
For scores measured on a nominal scale, a bar chart is the most appropriate frequency distribution graph. This type of graph displays categories as distinct bars, allowing for easy comparison of the frequency of each category. Since nominal data represents qualitative differences without any inherent order, the bars should not touch, emphasizing that the categories are separate and unrelated.
What is mode in class interval?
The mode in a class interval is the value or range that appears most frequently within that interval. It represents the highest peak of frequency in a grouped frequency distribution. To find the mode of a class interval, you typically identify the class with the highest frequency and then apply a formula to estimate the exact mode value within that class. In essence, it helps to determine the most common value in a set of grouped data.
What is the most important distribution in the galaxy and is widely used in all kinds of statistical inference?
The Gaussian distribution is the single most important distribution.
What is non normal distribution?
A distribution that is NOT normal. Most of the time, it refers to skewed distributions.
What type of graph best displays range and frequency?
A histogram is the best type of graph to display range and frequency. It visually represents the distribution of data by dividing it into intervals (or bins) and showing how many data points fall within each interval. This allows for easy identification of patterns, such as the most common values and the spread of data.
Type of frequency distribution most commonly found in quality work?
Bionomial
What is a negative frequency distribution?
If most the population has many high scores, the distribution is negatively skewed. If most have many low scores, it is positively skewed
If a frequency distribution has open-ended intervals at the extremes which measure of central location is the most difficult to estimate?
mean
What kind of frequency distribution graph shows the frequenciesClassrooms in the psychology department are numbered from 100 to 120. A professor records the number of classes held in each room during?
A histogram would be the most appropriate type of frequency distribution graph to show the frequencies of classes held in each psychology department room. Each classroom number (100-120) would be represented on the x-axis, and the frequency of classes held in that room would be shown on the y-axis.
What is a positively skewed distribution?
A positively skewed or right skewed distribution means that the mean of the data falls to the right of the median. Picturewise, most of the frequency would occur to the left of the graph.
Why are unequal intervals used in a frequency distribution?
The most important thing in creating intervals for a frequency distribution is that the intervals used must be non-overlapping and contain all of the possible observations. They are often equal intervals, but sometimes unequal ones are used. It all depends on the data.
What are the standard units for frequency?
hertz Hz
How do you calculate count frequency?
To calculate the frequency of counts in a dataset, you count the number of occurrences of each unique value in the dataset. This helps you understand the distribution of values and identify the most common or rare occurrences within the dataset.
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
How is frequency distribution useful to us?
I suspect you are referring to a sample frequency distribution.Providing that the sample size is sufficiently large there are various kinds of information that can be gleaned from one:the approximate range of values in the populationthe location of the population as measured by the value that appears most often in the frequency distribution-known as its modethe likely shape of the population's distribution, in particular whether it is symmetric or skewedobviously how values of the population variable are distributedwhether there are any curious peaks or valleys, even when the sample size is largethe amount of variation around the central value
What frequency distribution graph is appropriate for scores measured on a nominal scale?
For scores measured on a nominal scale, a bar chart is the most appropriate frequency distribution graph. This type of graph displays categories as distinct bars, allowing for easy comparison of the frequency of each category.

What does standardise mean?
To make objects that are considered to be the most usual or common size or form of their kind. It is a rule that is used for a basis of judgement
