Consider the variable “Product Rating”. Construct a frequency distribution for this variable using the classes (0.5, 1]; (1, 1.5]; (1.5, 2]; (2, 2.5]; (2.5, 3]; (3, 3.5]; (3.5, 4]; (4, 4.5]; (4.5, 5] and answer the questions that follow.

Beskou die veranderlike “Produkgradering”. Stel ‘n frekwensieverdeling vir hierdie veranderlike op deur die klasse (0.5, 1]; (1, 1.5]; (1.5, 2]; (2, 2.5]; (2.5, 3]; (3, 3.5]; (3.5, 4]; (4, 4.5]; (4.5, 5] te gebruik en beantwoord die vrae wat volg.

The number of values (frequency) between 2.5 and 4 are:

/

Die aantal waardes (frekwensie) tussen 2.5 en 4 is:

The percentage values that are more than 3 are:

/

Die persentasie waardes wat meer is as 3 is:

The first four coordinates of a frequency polygon are:

/

Die eerste vier koordinate van 'n frekwensieveelhoek is:
