Answer 1

Answer:

1)To find the mean, median, mode and midrange for each gender.

From the given data,

Male: 191,222,168,154,178,155,190,170,178,202,169,184,149,160,181,158

For Men:

Mean is,

$=\frac{191+222+168+154+178+155+190+170+178+202+169+184+149+160+181+158}{16}$$=\frac{2809}{16}=175.5625$

Mean is 175.5625

Arrange the given data in ascending order,

149,154,155,158,160,168,169,170,178,178,181,184,190,191,202,222

Median is,

$=\frac{170+178}{2}=174$

Median is 174

The mode is one of the values of the measures of central tendency. This value gives us a rough idea about which of the items in a data set tend to occur most frequently.

Mode is 178.

Female: 136,160,101,126,119,165,102,135,137,140,115,126,140,121,124

For Women:

Mean is,

$=\frac{136+160+101+126+119+165+102+135+137+140+115+126+140+121+124}{15}$$=129.8$

Mean is 129.8

Arrange the given data in ascending order,

101,102,115,119,121,124,126,126,135,136,137,140,140,160,165

Median is 126

Mode is 126,140
