How to find fixi in satastics

Answer 1

Answer:

to find xi:

(upper class+lower class)/2

frequency is given.

to find fixi

multiply Fi and xi

Answer 2

Fixi in statistics can be found by multiplying frequency with respective class intervals.

• Classmark = (upper limit + lower limit)/2 and fi = frequency.
• On multiplying classmark with the frequency we get the vale of fixi.
• The upper limit is the highest value of the class interval.
• The lower limit is the lowest value of the class interval.
• Fixi values are used in many formulas of statistics to find the required values.
