What is Modal class interval?
The modal class interval is the range within a frequency distribution that contains the highest frequency of occurrences. It represents the group of data points where the values are most concentrated. In a histogram or a grouped frequency table, the modal class is identified as the interval with the greatest number of observations. This concept is useful in statistics for understanding the most common range of values in a dataset.
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.
What kind of chart uses rectangles to show frequency distribution?
A histogram uses rectangles to represent the frequency distribution of a dataset. In a histogram, the width of each rectangle corresponds to the interval of values (bins), while the height indicates the frequency of data points within that interval. This visual representation helps to identify patterns, such as the shape of the distribution, central tendencies, and variability within the data.
What breaks the range of values of a variable into classes and displays only the count or percent of the observations?
A frequency distribution breaks the range of values of a variable into classes, known as bins or intervals, and displays the count or percentage of observations within each class. This statistical tool helps summarize data and makes it easier to identify patterns, trends, and the overall distribution of the variable. It can be represented in tables or graphical forms, such as histograms.
How do you find the interval for a set of data?
You find the the smallest and largest values. The interval is the largest minus the smallest.

Which interval contains the fewest data values?
Which contains the fewest data values
What is the number of values that lie in an interval?
The number of values that lie in an interval depends on the specific range and how it is defined. Generally, it can vary from zero values to an infinite number of values within the interval.
What is a sentence for class interval?
class interval - one of several convenient intervals into which the values of the variate of a frequency distribution may be grouped.
What type of graph best displays 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.
Why you need to measure extremely small interval of times?
We need small values of delta t as the smaller is the time interval better resolution of signal is possible. Also, the highest frequency in frequency domain is inversely proportional to delta t. So higher delta t in time domain results in higher the maximum frequency in frequency domain.
Does cumulative frequency show distribution?
Not directly, but the cumulative frequency contains the same information as the frequencies for the values in question. However, it may not show the full details of the distribution if the values have been grouped.
What kind of chart uses rectangles to show frequency distribution?

In a histogram, the width of each rectangle corresponds to the interval of values (bins), while the height indicates the frequency of data points within that interval.

What percentage is 1.5 standard deviation?
The interval of 1.5 sd either side of the mean contains 87 of the values of a Gaussian distribution. For other distribution the answers will be different.
What breaks the range of values of a variable into classes and displays only the count or percent of the observations?
A frequency distribution breaks the range of values of a variable into classes, known as bins or intervals, and displays the count or percentage of observations within each class. This statistical tool helps summarize data and makes it easier to identify patterns, trends, and the overall distribution of the variable.

What displays the lowest values for a range of values in excel?
The MIN function.
How do you find the interval for a set of data?
You find the the smallest and largest values. The interval is the largest minus the smallest.
