Observe the given data of the height of 15 studetns (in cm 146, 139, 135, 136, 149, 166, 164, 152, 163, 141, 171, 155, 144, 159, 146 Match the lists : {:(" List - I ", " List - II" ),(" (i) Range of the data is "," (p) 151 . 0 6 cm "),(" (ii) Mean height of the students is "," (q) 146 cm "),(" (iii) Median of the data is "," (r) 36 cm "),(" (iv) Mode of the data is "," (s) 149 cm "):}

Following is the height of 10 students: {:("Students",A,B,C,D,E,F,G,H,I,J),("Height(cm)",155,153,168,160,162,166,164,180,157,165):} Calculate arithmetic mean using Direct and Short-cut Methods.

The heights of 50 students , measured to the nearest centimetres, have been found to be as follows : {:(161,150,154,165,168,161,154,162,150,151),(162,164,171,165,158,154,156,172,160,170),(153,159,161,170,162,165,166,168,165,164),(154,152,153,156,158,162,160,161,173,166),(161,159,162,167,168,159,158,153,154,159):} (i) Represent the data given above by a grouped frequency distribution table, taking the class intervals as 160-165,165-170 ,etc.

The heights (in cm) of 30 students of class VIII are given below: 155,158,154,158,160,148,149,150,153,159,161,148,157, 153,157,162,159,151,154,156,152,156,160,152,147,155,163,155, 157,153 Prepare a frequency distribution table with 160-164 as one of the class intervals.

The heights (in cm) of 30 students of class VIII are given below: 155,158,154,158,160,148,149,150,153,159,161,148,157, 153,157,162,159,151,154,156,152,156,160,152,147,155,163,155, 157,153 Prepare a frequency distribution table with 160-164 as one of the class intervals.

The heights (in cm) of 30 students of class VIII are given below: 150,152,154,152,148,149,150,155,159,160,152,154,160,149,150,152,155,145,154,145,148,153,155,150,160,154,152,149,152,148. Prepare a frequency table with 160-164 as one of the class intervals

The following table shows the heights of 50 students of a class : {:("Height (in cm)",152,148,150,153,149,151,147),("Number of students",8,3,4,7,12,10,6):} Find the mean and the median. Using empirical formula, calculate its mode.
