Reflecting on May's weather data

I collected data on May's weather when growing my sunflower. I kept track of high temperature, low temperature, temperature range and whether or not there was rainfall.

High Temperature: I found the mean of the data by adding the temperatures together (1090) and dividing by the number of days that I collected data (15). The mean (average) high temperature was 72.7 degrees Farenheit. The mode (or most common) high temperature in May was 72. The median was 72 degrees as well, which I found by arranging the temperatures from least to greatest, then crossed off one number on each side of the data until I reached the middle. The Range of data was 32 degrees, quite a big difference in the high temperatures over 15 days.

Low Temperature: I found the mean of the data by adding the temperatures together (756) and dividing by the number of days that I collected data (15). The mean (average) low temperature was 50.4 degrees Farenheit. The mode (or most common) low temperature in May was 51. The median was 51 degrees as well, which I found by arranging the temperatures from least to greatest, then crossed off one number on each side of the data until I reached the middle. The Range of data was 31 degrees, I found that by subtracting the lowest temperature from the highest low temperature.

Rain: In May there were five days with rain, two days with drizzle and eight days with no rain.
