Relative frequency – is how often something happens divided by all outcomes.
We have the frequency distribution of the chips “Pringles” at 40 different shops.
|Price for 1 bank of chips||Number of shops|
Find the relative frequency for shops prices.
According to the given information, we can build a relative frequency for shops prices:
|Price for 1 bank of chips||Number of shops||Relative frequency (fraction)||Relative frequency (percent)|
|$23.50–$23.74||11||11/40 = 0.275||27.5%|
|$23.75–$23.99||9||9/40 = 0.225||22.5%|
|$24.00–$24.24||10||10/40 = 0.25||25%|
|$24.25–$24.49||10||10/40 = 0.25||25%|
With a sample size of 40 shops, we have divided each number of shops by 40. The result can be written as a fraction or as a percentage. For example, 25% of shops have relative frequency of prices between $24.25 and $24.49.
We have the weight of 100 persons in the school. We should find relative frequency for each weight limits.
|№ of persons||6||17||40||29||8|
The relative frequency for each weight limits is shown in table below:
|Relative frequency table|
|Weight (kg)||№ of persons||Relative frequency|
|60-62||6||6/100 = 0.06 or 6%|
|63-65||17||17/100 = 0.17 or 17%|
|66-68||40||40/100 = 0.40 or 40%|
|69-71||29||29/100 = 0.29 or 29%|
|72-74||8||8/100 = 0.08 or 8%|
The lowest frequency is for the weight 60-62 kg, and the biggest – is for the weight 66-68 kg.
