Question

Presenting Data in a Report (CHOOSE 1) 3. [16 pts] Find 8 errors or corrections needed to improve the data sets presented in the table and graph below la total of 8 between the two). Circle the incorrect item and then number it. Below at the corresponding number indicate what the error is and provide feedback to the "student" for what they should have done to correctly represent the data.

Explanation / Answer

The Relationship between pH value,Tempa and Hardness of water. If increse the temparature the pH value is decrese and the same time hardness of water is depends up on the minerals content. The mineral acts is more the pH value is more and the mineral act is lees is the pH value is Lower. So we are called greater than 7 pH value is alkanity and less than 7 pH value acidity.

Erros/Correction: 1. If you see the above table you observe sample 2 and 3 at well water value of pH value, temp and Hardness. If the temparature increse and at the same time the pH value decrese wright but the hadness is same for sample 2 and 3.

2. If you observe surface water sample 1 and 2 the pH values same but temparature and Hardness is changed

3. Sample 3 at surface water of temparature is incresed more but pH value is reduced very less.

4. Observe surface water sample 3 and 4 of pH value and temparature is changed but hardness is same.

5. If you observe the sample 2 of tap water the pH value is 20. actual range from 6-10.

6. If you see the sample 1 and 2 of tap water the pH values and temparature are same but the is changed.

7. If you see the sample 4 of tap water the hardness is crossed more value sa compare to all the samples of tap water.
