What is an 'ungrouped frequency table'?
A frequency distribution of numerical data where the raw data is not grouped.
Is the mean of the grouped data is equal to the mean of ungrouped data?
Suppose you compare the mean of raw data and the mean of the same raw data grouped into a frequency distribution. These two means will be
When should measures of location and dispersion be computed from grouped data rather than from individual data values?
The main need to work with grouped data was to reduce the number of data points that need to be stored and processed in calculation. With modern computers the storage and computation are not likely to be issues in many situations and so there is no need to use grouped data.
What is a grouped frequency table?
A grouped frequency table is a statistic method to organize and simplify a large set of data in to smaller groups.
What property can you use to change the way three factors are grouped?
Commutativity.
Definition of ungrouped data?
Ungrouped data is data that is not grouped in a specific order. Grouped data is a set of data that has unique characteristics in common.
Calculating quartile deviation for grouped and ungrouped data?

What is an 'ungrouped frequency table'?
A frequency distribution of numerical data where the raw data is not grouped.
what are the advantages of using a grouped data over an ungrouped data?
Nothing, they stealing yo data
Formula for grouped and ungrouped data?
ungruped data are those type of data which are not proper arranged or order
What are the advantages of measures of central tendency?
Central TendencyIn central tendency the large group of data is grouped into a single value for effective business decision making.
What is formula of deciles?
D=E1+((dN/10)-Cf)(I)/F The formula of deciles is different for grouped and ungrouped data.
How do you get the class interval for ungrouped data in statistics?
same as grouped data i.e. (upper limit+lower limit)/2
Why ungrouped data more accurate?
Ungrouped data is often considered more accurate because it retains all the original values without any loss of detail that can occur during the grouping process. When data is grouped, some nuances and variations within the data set may be obscured, potentially leading to misleading interpretations or conclusions. Additionally, ungrouped data allows for more precise calculations of statistical measures, such as mean and standard deviation. Therefore, ungrouped data provides a clearer and more comprehensive picture of the underlying information.
Is the mean of the grouped data is equal to the mean of ungrouped data?
Suppose you compare the mean of raw data and the mean of the same raw data grouped into a frequency distribution. These two means will be
Grouped data and ungrouped data in Statistics?
In statistics, ungrouped data refers to raw data points that are presented individually, allowing for detailed analysis and precise calculations, such as mean and median. In contrast, grouped data is organized into classes or intervals, which simplifies representation and analysis, particularly for larger datasets, but may obscure specific values. Grouped data is often displayed in frequency tables or histograms, while ungrouped data is typically shown in lists or scatter plots. Each type has its own advantages, depending on the context and goals of the analysis.
What are the categories by which data are grouped?
Data can be grouped or ungrouped. The categories data are grouped in depend on the data. For example, data collected about people could be grouped as male/female, by ages, or some other common characteristic. Data collected about dogs could be grouped by breed of dog, age, long hair/short hair, or size.
