How can I create a histogram from this data set: one for average age starting to crawl in weeks and the other for average temperature 6 months after birth? I cannot just highlight each set of data in Excel then click insert histogram because it only gives me two bars and I need more bars in order to establish if these would be considered normal data distribution.

Month	Average Age Starting to Crawl (weeks)	Average Temperature 6 Months After Birth Month (in units Fahrenheit)
January	29.84	66
February	30.52	73
March	29.7	72
April	31.84	63
May	28.58	52
June	31.44	39
July	33.64	33
August	32.82	30
September	33.83	33
October	33.35	37
November	33.38	48
December	32.32	57
