calculate the mean median and mode using the grouped data for heart rate. Interpret your result.

Question

Each subject's heart rate is also recorded in the same sequence as their time score.

63	89	75	80	74	65	90	85	92	84
74	79	98	91	87	76	82	90	93	77
74	89	85	91	102	69	87	96	83	72
92	88	85	68	78	73	86	85	92	90

1. Organize data for the heart rate into frequency table, displaying both the raw and cummulative frequencies and the mid- points of this class intervals. Same class intervals given in item # .

2. calculate the mean, median and mode using the grouped data for heart rate. Interpret your result.
