Chapter:05 (Statistics)

Question 1:

The sum of all variables divided by their number is called

Median Arithmetic Mean Mode Geometric Mean

Question 2:

When n is odd \({(\frac{n+1}{2})}\)th value is called

Mean Mode Median Harmonic Mean

Question 3:

The formula \(x ̃\,=\,l\,+\,\frac{h}{f}\,({\frac{n}{2}-c)}\) is used for finding

Median for grouped data Arithmetic Mean Geometric Mean Mode

Question 4:

The formula \(x ̃\,=\,l\,+\,\frac{h}{f}\,({\frac{n}{2}-c)} \,\, l\) denotes

class interval lower class boundary of the Median class frequency of the Median class commulative frequency preceeding to the Median class

Question 5:

The formula \(x ̃\,=\,l\,+\,\frac{h}{f}\,({\frac{n}{2}-c)} \,\, h\) denotes

Total number of frequency Lower class boundary of the Median class Class interval Frequency of the Median class

Question 6:

The formula \(x ̃\,=\,l\,+\,\frac{h}{f}\,({\frac{n}{2}-c)} \,\, c\) denotes

class interval commulative frequency preceeding to the Median class number of frequency frequency of the Median class

Question 7:

A value which occurs maximum number of times in the data is called

Mean Geometric Mean Harmonic Mean Mode

Question 8:

The formula \(l\,+\,\frac{{f_m}-{f_1}}{({f_m}-{f_1})({f_m}-{f_2})}\,×\,h\) is used for finding

Mode for grouped data Median Mean Geometric Mean

Question 9:

Mode can be calculated by the formula

Mode = 3 Median - 4 Mean Mode = 4 Median - 3 Mean Mode = 3 Median - 2 Mean Mode = 2 Median - 3 Mean

Question 10:

The formula for calculating Standard Deviation is

\(\sigma\,=\,\sqrt{\frac{\sum(x-\bar{x})}{n}}\) \(\sigma\,=\,\sqrt{\frac{\sum({x^2}-\bar{x})}{n}}\) \(\sigma\,=\,\frac{\sum{x}}{n}\) \(\sigma\,=\,\sqrt{\frac{\sum{({x}-\bar{x})}^2}{n}}\)

Question 11:

The formula for calculating Standard Deviation for grouped data is

\(\sqrt{\frac{\sum{f}(x-{\bar{x}})^2}{\sum{f}}}\) \(\sqrt{\frac{\sum{f}(x-{\bar{x}})}{\sum{f}}}\) \(\sqrt{\frac{\sum{f}({x^2}-{x})}{\sum{f}}}\) \(\sqrt{\frac{\sum{f}(x-{\bar{x}}^2)}{\sum{f}}}\)
