## How do you find the unknown frequency in statistics?

Apply the formula: – Median = L+(N2−cff)×h, where L = lower class containing the median, N = total student, f = frequency of the class containing median, cf = cumulative frequency before the median class, h = class interval, to calculate the value of x.

## What does frequency mean in statistics?

absolute frequency

## How do you complete a frequency table?

To construct a frequency table, we proceed as follows:

- Construct a table with three columns. The first column shows what is being arranged in ascending order (i.e. the marks).
- Go through the list of marks.
- Count the number of tally marks for each mark and write it in third column.

## What is included in frequency table?

Included in a frequency table are typically a column for the scores and a column showing the frequency of each score in the data set. However, more detailed tables may also contain relative frequencies (proportions) and percentages.

## What do frequency tables display?

These displays show all possible values of the variable along with either the frequency (count) or relative frequency (percentage). Relative frequencies are more commonly used because they allow you to compare how often values occur relative to the overall sample size.

## Is a frequency table qualitative or quantitative?

Statistics that describe or summarize can be produced for quantitative data and to a lesser extent for qualitative data. As quantitative data are always numeric they can be ordered, added together, and the frequency of an observation can be counted.

## When would you use a cumulative frequency table?

Cumulative frequency is used to determine the number of observations that lie above (or below) a particular value in a data set. The cumulative frequency is calculated using a frequency distribution table, which can be constructed from stem and leaf plots or directly from the data.
